The server is running. I restart it via hardware buttons and I get emails from monit telling me X and Y has happened. My PiHOLE is running (via docker). I can see that's working (as my DNS would fail it it weren't). It's all there.
However if I try to go to it via say 192.168.20.11:8090/ (for heimdall) or 192.168.20.11 (for OMV admin panel) nothing happens. I just eventually get a time out. I can't SSH to it either. Same problem.
I'm stumped. Restarting doesn't do anything. What can I try please, to get access again?
