Is this ok? ERROR Exception: Failed to fetch block

Support
1

From time to time I get this type of error:
ERROR Exception: Failed to fetch block

  • I managed to port forward 8444 and the system is now perfectly reachable from the outside.
  • Running Chia GUI on Ubuntu installed via the experimental installer.
  • On the same network I have two other windows machines running Chia GUI but they have UPnP disabled in config.yaml to avoid conflicts.

I’ve set the log to INFO but didn’t restart chia yet, so here is what I got so far in the log:

I’ve cleaned some IPs from the log, don’t know if posting them is a good idea

Yes because Full Nodes go offline and online all the time. Not sure what the banning is about yet. It usually says they’re running old software or a different protocol.

Oh wow thanks again for the info! :slight_smile: very kind.

So I am not doing anything wrong running multiple Chia GUI in the same network having UPnP enabled only in one of them?

Maybe it’s not the best practice but it shouldn’t create conflicts, right?
