bor can not sync

[EronTo]

I'm facing a persistent issue with my BOR client failing to sync correctly. The following log messages keep appearing repeatedly:

System Details:

curl -s -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"net_peerCount","params":[],"id":1}' http://127.0.0.1:8545 I get the following response:

Could anyone help me diagnose and resolve this issue? Any guidance or suggestions would be greatly appreciated!

The same parameters and config, and the same problem

[tennnessse]

i have same problem

[feld]

^^ do not follow that scam link

Can we get survey of where the servers are? Mine hosted with AWS have the syncing issue too. I've been struggling with this since late March when 1.3.0 was released as we used to have no problems getting 200 peers back then

I never had 200 nodes connected, the most I ever had was around 40, and now I have temporarily started syncing normally by adding peers

[hdiass]

Problem still exists on every bor node. When you guys can fix this issue ?

[piccadil]

The same issues on the same versions of the bor and heimdall.

[darkhorse-spb]

same problem here

[valamidev]

We are still using 1.2.X, to avoid this issue.

[OldBorrow1488]

Мы по-прежнему используем 1.2.X, чтобы избежать этой проблемы.

what versions do you use to solve this problem, can you tell us more?

1.2.8 Bor + 1.0.4 Heimdall and used the used the last Snapshot provided by Polygon team. Took about ~3 weeks to sync.

[piccadil]

I downgraded a node to 1.2.8 Bor + 1.0.4 Heimdall, and started to sync for about 10-15 minutes, then I got the same error err="missing blocks"

Are you working from snapshot or sync from 0?

[valamidev]

This err="missing blocks" remind me a common issue with other chains, once your Node was killed or not gracefully shutdown your chaindata getting corrupted there is no any other sign for that unless it will never sync anymore.

[piccadil]

I'm working from a snapshot. It was on version 1.3.3, synced for a couple of weeks, then stopped to sync. After restart, it syncs for 5-10 minutes, and then I get this error.

I got the same issue

[Brindrajsinh-Chauhan]

Facing the same issue with the same version and config. Any solution/fixes?

[sduchesneau]

This fixed it for me (seems these 3 issues are duplicate) https://github.com/maticnetwork/bor/issues/1239#issuecomment-2235835196

my node 1.3.3 was stopping synching as soon as is reached the HEAD (it seems it could only sync historically...) then, deleting nodekey, nodes/ and starting with bootnodes ( I took a few bootnodes from a node running on 1.2.8 that was working).

[anshalshukla]

Recent release seems to have fixed the above mentioned issues. Feel free to reopen the issue if it still persists.
