Problem syncing node with error - Refused NodeToNodeV_6 "version data mismatch: NodeToNodeVersionData

My first post here, searched for similar issue but didn’t quite find any. So, please forgive me if I missed a similar post here. I am setting up a stake pool in testnet.

Running on Azure, using terraform to setup infrastructure, have 2 nodes with 2 core and 4GiB each. cardano-node is running in a docker container.

I am following through the coincashew guide and got my node to start syncing the blockchain on low grade VM. Realized it will take 4 days to fully sync up. So, Upgraded my VM (2 core and 4GiB) and started the container like before but now I am getting the below error. No “Chain extended, new tip” message, just the below error message over and over again. The block producer node is also not moving forward.

Relay node topology points

"addr": "relays-new.cardano-mainnet.iohk.io",
"port": 3001,
"valency": 2

Does anyone know what could be the issue here?

On the relay node, I also see this error message along with the previous messages:

[rly1:cardano.node.ErrorPolicy:Notice:56] [2021-06-18 23:30:07.06 UTC] IP 54.179.126.222:3001 ErrorPolicySuspendConsumer (Just (ConnectionExceptionTrace (SubscriberError {seType = SubscriberParallelConnectionCancelled, seMessage = "Parallel connection cancelled", seStack = []}))) 1s

Turns out the problem was with my script automation where I create the initial topology file. After manually creating it, it is syncing the blockchain as expected.

I am going to look into the automation I created. The issue is now resolved.

Hi!

btw, you can mark your post as solution.
