Chia how to sync

Syncing Problems on Windows

The Chia network is developed by Bram Cohen, the inventor of BitTorrent. As such, the Chia Client uses a peer-to-peer network to download the blockchain. Recently however, there has been an explosion of new people wanting to farm Chia. This means that the synchronization times of the blockchain is going through the roof. We’re talking hours here. To help mitigate this, there are a few things you can do to ensure that you have no roadblocks in the way.

I will be a bit high-level on this subject because there are so many configurations out there that I can’t possibly cover them all. Hopefully this will point you in the right direction. If you are having synchronization issues, perform the following:

1. Windows Firewall – Make sure that the chia client is allowed through the firewall. A no brainer, but doesn’t hurt to check.
2. Router update – Install the latest update to your router. This isn’t required, but it has helped some people fix their sync issue.
3. UPNP errors – Check the Chia Client log and make sure you don’t have any UPNP errors. If you don’t know what I’m talking about, follow this and come back. Just search the log for “UPNP”. If you do have UPNP errors, this means your router does not have it enabled (which is good security-wise) but bad for the Chia Client. Essentially, only you can connect out to peers but no one can connect to you. Plus you will be limited to 10 peers instead of 50. To fix this, and keep UPNP disabled on the router, you must Forward port 8444 in your router. Then you must change the config file to disable UPNP by changing the following value:

Restart the Chia Client when this is complete.

4. Timezone Settings – Make sure that your time is correct. On Windows, if you have “Set Time Zone Automatically” selected, it may cause sync issues due to incorrect time. Turn off “Automatic Timezone” but keep “Automatic Time”. Manually Select your Timezone to the correct one. Then Synchronize the time with the Windows Time Server.

5. Router on Router? – Some people have a modem/router combo from their ISP for their internet service. Then, they piggy back their own router off this one. If this is you, remember that if you forward port 8444 on your router you also have to forward it on the ISP modem/router.

6. Port Check – Once port 8444 has been forwarded, you need to check if the port is actually open from the outside. Go to this website and enter port 8444 to check. It should fill out your Public IP address automatically: https://www.yougetsignal.com/tools/open-ports/

Edit: Thank you to Anees in the comment section for making me realize I was missing step 6.

7. Add A Chia Introducer – This is a Last Resort. If you are still having sync issues and not connecting to peers, add one of the following IP address in your Chia Client. These are listed on the Chia Teams GitHub page. Don’t add all of them (Thanks willphule!) Just click the “Connect to other Peers” button in the Chia Client and add the IP/port:

These are the things you can do and check to ensure that there are no roadblocks preventing the syncing of the block chain. As I come across more solutions, I will add them to this page.

More on sync – part 2.

This is somewhat a continuation of the first post about sync in general that you can get here: https://www.chiablockchain.com/2021/04/26/sync-problem-what-shall-i-do/

As the chain is getting bigger and bigger – currently the height is 293742 and if you are new or out of sync for a while it can take quite some time to get back to sync.

Full node sync / Wallet sync

Yes, so you need to worry about two types of synchronization, if you have been having trouble getting your full node back to sync than Wallet syncing will drive you crazy :). The good thing is Wallet sync does not impact you winning and Full node sync does not impact you to plot.

• Wallet sync – required to see the amount XCH you have and to be able to transfer and receive XCH.
• Full node sync- required for you to be able to participate in the lottery and be able to win if you are farming.

Wallet sync takes a lot of time, it actually lot longer than getting your full node synced.

Do I really need UPnP and/or open port 8444?

Yes and no. Chia is a distributed system so instead of the chia network owning/running/maintaining and keep growing the number of servers they have they use the full nodes on the network – like us minions to help distribute the load. If you open this port than you are helping chia but if you don’t open this port you can still be in sync. To help the network I highly recommend to accept some connection, so please open port 8444.

Why sync is an issue? Why you need to worry about it?

I don’t know for sure but upon looking at the logs the problem is that chia tries to connect to introducer.chia.net and nothing else. If this server has too many connection then yours will be rejected and you need to keep retrying until you succeed. I think the way it’s done once your node is “introduced” and you have other established connections then introducer.chia.net will drop you.

How can I get back in sync the faster?

You need the chia CLI:

cd /$where/$you/$have/$cloned/$chia/
. ./activate
./chia

chia show -a 5.189.201.93:8444;
chia show -a 101.66.242.200:8444;
chia show -a 91.5.105.207:8444;
chia show -a 188.75.237.73:8444;
chia show -a 222.90.142.21:8444;
chia show -a 36.25.92.92:8444;
chia show -a 109.127.49.163:8444;
chia show -a 100.34.155.23:8444;
chia show -a 92.234.80.105:8444;
chia show -a 103.20.120.53:8444;
chia show -a 180.183.121.18:8444;
chia show -a 99.250.171.171:8444;
chia show -a chiadb.net:8444;
chia show -a node.chia.net:8444;
chia show -a node-eu.chia.net:8444;
chia show -a introducer-apne.chia.net:8444;
chia show -a introducer-apse.chia.net:8444;
chia show -a introducer-or.chia.net:8444;
chia show -a introducer-va.chia.net:8444;
chia show -a introducer-eu.chia.net:8444

To verify your connection status:

One thing that happened with me is that I had multiple wallets. Given each wallets has it’s on SQLlite DB that requires to be synced I was thinking to get rid of one of them. Once I deleted the wallet I no longer need (wallet I used to plot but then moved the plots to Hpool) things got more stable. Running the latest version (1.1.5) and slowly but gradually it is syncing. Good thing is I saw the chia team is active and working on a fix but until you can try this:

Since today its always Not Synced, and there is no connection to Full Node peer
I can manualy add connection, its go OK for about hour or so, and then again Not Synced, and connection just gone from the list

Windows 10, time sync — OK

Have you tried adding a port forwarding in your router on port 8444 to your PC? Or maybe add a different introducer:

Introducer

• North Asia introducer-apne.chia.net:8444
• South Asia introducer-apse.chia.net:8444
• Western North America: introducer-or.chia.net:8444
• Eastern North America introducer-va.chia.net:8444

Yeah i did
It connect, go for sync, and then Not Synced again
Strange thing, that for 2 days it works perfectly fine, i got fully synced, and start Farming.

is the height in the Wallets tab as high as the peak height in the Full Node tab? If it does, here ends my wisdom, sorry

rjulius23 commented Apr 29, 2021

Ok my experience is that node.chia.net is super flaky. Sometimes i can connect to it forcefully, sometimes it just rolls and nothing happens. I think the issue is central, do not think it is a client issue.

rjulius23 commented Apr 29, 2021 •

Can we prioritize this issue ?

filippovpa commented Apr 29, 2021

i cant even ping node-eu.chia.net
is it down ?

Has been down for 2 hours now. 🙁

Wardus commented Apr 29, 2021

I have this same problem. It shows me as connected, but my status is Not Synced. HELP!

fiveangle commented Apr 29, 2021

Seeing same thing here. All non-port mapped nodes fall out of sync regardless of the introducer. Also, chia show -a :8444 results in that node refusing to stay connected.

Seems the P2P part of the Chia network is fundamentally not functioning consistently.

filippovpa commented Apr 29, 2021

rjulius23 commented Apr 29, 2021

Using chiadb.net:8444 solved it for me, however the root cause is still unknown as node.chia.net:8444 worked fine for 2 weeks.

rjulius23 commented Apr 29, 2021

Looking deeper into the issue, I think something with UPnP went fishy. I will play around with the UPnP settings in my router and in the chia node to see if that is the culprit.

filippovpa commented Apr 29, 2021

Finaly got sync in progress!! Thx a lot mate, ur my savior =)

RollingRoland commented Apr 29, 2021

I have a similar problem. After I installed Chia 10 days ago things worked without any special router setup. But since 24 hours it is not syning or farming anymore. I tried everything in my shitty router to open the ports. It is a TP Link Archer C7. The closest I could find there was a port trigger option where tried to open the port. It does not seem to work. I also tried to manually add nodes and introducers in the GUI. After a few circles the window just disappeared and nothing happened. And on the 2 try on manually adding an introducer the window just hung itself and kept circling. After clicked the «restart» option the whole GUI is hung circling now. The Chia GUI is so full of bugs like I have never seen before. Unfortunately I am not an IT or Network specialist. So can’t say I grasp on how to use CLI properly. I am really at the end of my wits. Any help would be much appreciated.

Full node status not synced[BUG] #4217

Comments

Damaka5 commented May 8, 2021 •

I have a problem with chia cliet. In the last 1,5 weeks it worked with no problems, but in the last 3 days the full node is not synced. I have a second PC in my network plotting too, and it is synced with no problem. I tried port forwarding, manually connect to peers, turn on-off upnp, restart client, restart PC, I´m even turned off the chia client on my second PC, but still nothing. If i turn on the client on my second PC, almost instantly start to sync while on my primary PC it not syncing at all. I have the latest (1.1.4) and same version on both. Nothing has changed on my primary PC. Can you please help me with that?

Can confirm the same issue. For last 2 weeks had no problems with sync, but since last 10 hours got not synced. Please fix it, it doesn’t allow to farm

boguhft commented May 8, 2021

Same issue here. I tried everything

IsaEs commented May 8, 2021

Same issue not synced.I tried to connect peers and restart several times doesn’t work.

SGABR commented May 8, 2021

Vou postar em português mesmo. Usem o tradutor para sua língua.

Até onde pesquisei o problema pode estar nos arquivos blockchain_v1_mainnet.sqlite e no peer_table_node.sqlite que ficam em:

e também nos arquivos blockchain_wallet_v1_mainnet_[#dacarteira].sqlite e no wallet_peers.sqlite que ficam em:

Estes arquivos armazenam os dados de altura do pico de sincronização que aparece na GUI do Chia.

Quem esta usando a GUI em dois ou mais computadores, pode ter problemas não desabilitar o uPnP, conforme descrito no item 4 em:

Este era o meu caso. Estava usando dois PCs, um fraco para o cultivo e outro forte para a plantação, conectados na mesma carteira, No PC fraco, desabilitei o uPnP.

No entanto, mesmo assim, hoje de manhã perdi o sincronismo nos dois PC e ao verificar o log de erros (que pode ser encontrado em: C:\Users%USERNAME%.chia\mainnet\log\debug.log), achei vários erros do tipo:

ERROR Exception: , closing connection None. Traceback (most recent call last)

Imaginei que se trata de problemas nas bases de dados do PC fraco e do PC forte, pois ambas estariam dessincronizadas, então fiz um backup de todos os arquivos citados e pequei os arquivos que tinham o menor tamanho (que estavam no PC fraco) e substitui nos diretórios do PC forte.

A conexão foi reestabelecida e após uns 15 minutos sincronizando, já estava tudo ok.

Minha recomendação então é sempre fazer um cópia destes arquivos no momento em que esteja tudo ok e guardar para usar quando o problema ocorra novamente.

Outra coisa importante é verificar se você tem espaço no disco para que estes arquivos possam se expandir. Por padrão eles são colocados dentro do nosso perfil no Windows 10, então se você reservou pouco espaço para a instalação do Windows, poderá ter problemas futuros com a expansão destes arquivos.

Espero que ajude.

Saudações do Brasil!

finally synched, after nearly 24 hrs

holdenprkr commented May 9, 2021 •

I’m struggling with the error now as well. Does anyone know what it means if when I start syncing the peak height is under 12000? Does this mean anything? Anyways, once it reaches this point it finally turns to Not Synced. Starting from the CLI I can see it’s not synced immediately. I’m hoping this gets fixed soon I want to farm!

kuhnline commented May 9, 2021

Check your computer clock. My status changed to Not Synced and I ended up searching for answers and found this thread. Then I noticed my clock was an hour fast. I fixed the time and it instantly changed to Synced.

ChristmasWoe commented May 9, 2021

@kuhnline thank you for your reply, but my pc’s clock was never changed and is correct. Still waiting for fix or at least a comment from dev.

aviscido commented May 9, 2021

Had the same issue, with my farm running inside a VM. I’ve made sure to allow UPnP for the VM in my router and restarted the GUI client many times without success. I’ve decided to restart the VM — after restarting everything, it is now syncing.
Long story short, make sure port 8444 is open on the router and restart your ubuntu machine in case.

Same here. I have the port open and the clock ok. I’m connected to 25 full node peers, and still not synced

Damaka5 commented May 9, 2021

I deleted the whole client from my PC made a fresh install, newly added even the wallet to the client. Copyed the chia client files from a PC when it was synced and worked just fine. Now it looks like it will work because it started syncing. I will make an update if it’s going to work.

Johetan commented May 9, 2021

same here — cli plotting still works plots appear to still pass filters.

sku10 commented May 9, 2021

Same here. Just finished 4 plots and after the last one GUI shows Not Synced.

sku10 commented May 9, 2021

the software could have a ‘force retry sync now’ button or something.

You have to upgrade to 1.1.5 and restart node.

LuanPoi commented May 10, 2021

One thing have worked for me, I added the peers manually in my node, and almost instantly the sync start.

To do this just go to this site:

select some nodes and add them manually in the full node section in the GUI.

Damaka5 commented May 10, 2021

Looks like the version 1.1.5 solved the syncing problem!

spammenotinoz commented May 11, 2021

1.1.5 and will no longer find peers.
Clock in Sync = Check
Port Forwarding = Check
Firewall = Check
deleted peers DB = check
Managed to manually add in a known peer and it has synced, but has found no other peers in several hours.
Spun up a fresh VM, and it found peers with no port forwarding, no upnp.

spammenotinoz commented May 11, 2021

i woke up this morning and had the same problem. your 8444 port closed somehow. you need to go into your router settings and open it again. as long as you know how to get into your router settings, it is an easy fix. you need to port forward 8444
…

I can confirm the port was open as I could telnet to my Internet address remotely on port 8444.
I changed the helper name in the confit and that seemed to fix it, perhaps in my case the helper was down.

desdoo commented May 12, 2021

I have been told in the keybase channel to «connect to other peers» and enter «node.chia.net» «8444», which should resolve the issue.

antenape commented May 12, 2021 •

how come this kind of version can release?

joejoethejoey commented May 17, 2021

Just set up on a new system with blank M2 drive for plotting and a couple of USB 18tb drives. The full node status is jumping from «not synced» to «syncing». Will it need to restart syncing when it loses it?

It is now syncing 1600/297073.

Lazerus24 commented May 19, 2021

same problem here. no sync after 2 days.
faq says «The most likely reason is that there are no users with space to have new connections» so why do you even allow users with a blocked 8444 port?
Any chance to force all users to open that port?

After nearly three days, it finally completed the sync. I have no idea why it took so long. Could it really be due to massive growth over the last few weeks? All the guides and tutorials say sync only takes a few minutes or a couple of hours. I’m guessing this is if you already had a full sync once before. Can anyone comment on how long their very first sync took?

matthewjbauer commented May 20, 2021

For those asking how long the sync will take, well. I wondered the same thing. I have an Opteron HP 4 bay Raid server that I want to use as a mass storage Farming only server. It only has HDDs in its front facing RAID bays + the internal boot SSD. All the server will do for now is farm. I will use my Ryzen 2600 PC with 3x NVME SSDs for my main plotting. The Ryzen PC is syncing almost double speed of the HP server, but that is still slower than I have seen videos of. I think sync speed comes down to 3 main factors, your internet speed, the Processor speed, and RAM amount in your PC. Good news is that from what I can tell, plotting doesn’t effect sync speed, so you can plot away and not slow down syncing all that much.

Also, everyone should set their Windows clocks on automatic sync to the time server and let Windows manage the time based upon location. That should eliminate the issue of syncing failing based on location/time not matching.

It took me nearly 3 days to get a complete sync on my farming server on an Opteron storage server running Windows 2019. My Ryzen 2600 is going twice as fast but isn’t done yet. Sync speed has a lot to do with Internet speed and PC specs. I would NEVER try to do a sync on a raspberry pie if I planned to create a farming NAS (and I contemplated doing that with mine and 4x 4 or 8TB drives). I would instead copy the synced blockchain from my completely synced system (with the Chia app closed and all traces of Chia closed) to the pie and go from there.

Word of caution: if you find a download for a fully synced block chain or if you find a download for a .chia folder, DO NOT download it as I have heard that those could be bad copies.

I am now thinking to take advantage of the faster internet connection at my office. If I use a spare PC in the office and also plot and farm there, will this cause issues with my home plotter/farmer? I’ve read there could be syncing issues if more than one plotter/farmer. But what if it’s at different locations but using the same wallet?

I don’t know. I am scared to do it at my office. Even though I am the IT guy and I have an unrestricted network set up for users (mainly the company owner and people who pass my quiz), I still don’t want to do it and get caught by filtering by the director of corporate security and compliance.

I also don’t know about the issues associated with having multiple blockchains on the same account and having the blockchains not match and trying to farm multiple different updated blockchains. What I am doing is only farming on 1 version of the blockchain and not worrying about the sync on any other system I have and it being out of sync or not BECAUSE if and when I try to sync all other PCs, I can always shutdown all PCs on my network and boot up the good synced PC without Chia, copy the .chia folder to my unsynced (plotting only) PCs and see if that fixes it (it should eventually get the unsynced PCs fully in sync without having to go through the syncing process). DO NOT download a .chia folder or synced blockchain online, sync a PC yourself and let it verify before attempting to copy the .chia folder to any unsynced PC.
