reference client has different hash for block

[hazim-j]

I'm currently trying to run an Optimism Goerli node on an AWS EC2 instance. It's been running fine and staying in sync up until recently where it started showing the following logs in the healthcheck-bedrock service.

Any suggestions on the best way to debug this? Not sure if there's a way to rewind to before the first mismatched block?

Hello @hazim-j We had same problem with full and archive nodes

Not sure what happened, we tried to make a wipe and resync, but again stucked on same block

So, we run new ec2 instance with clear node setup with this flag (--p2p.disabled), and it's fully synced with blockchain

[hazim-j]

@almukhametovd what was the rationale behind using P2P.disabled flag?

We also spun up a new EC2 instance but with same config and it synched fine.
