Yesterday I had to take down my node unexpectedly for about 2h. In the meantime had to change DNS and updated the Docker container to version 1.10.1. All operations went pretty smoothly, but the restart my node is showing as offline. The tail of the log looks like this: 2020-08-31T07:41:14.172Z …

Found the solution! My fault, of course… Updated a secondary DNS zone and forgot to update the actual master one, therefore the DNS was still pointing to my old IP. Thanks for the support debugging the issue!

Node Offline... no idea why
