Steps to reproduce

  1. Yesterday, I updated the docker container “Uptime Kuma” from version 1 to version 2. During this migration process I lost the network connection to my dietpi. No ssh access was possible.
  2. … I’m not sure if it happens because of the docker container update but since yesterday the dietpi is not accessible via network from time to time. This off-time is for around 1-2 hours I guess. I do not check every minute, therefore I can not say something more accurate timing.
  3. But, after that the dietpi is connected again and I can see in my Grafana dashboard that the dietpi was working all the time. The connection is via LAN cable.
