MyOpenhab stops working

  • Platform information:
    • Hardware: raspi 2
    • OS: raspbian
    • Java Runtime Environment: OpenJDK Client VM version 11.0.13+8-LTS
    • openHAB version: 3.3.0
  • Issue of the topic:
    Since about 2 weeks, my remote server is stopping.
    i noticed this last week and i saw in MyOpenhab that the server stopped working 13 days before.
    i searched the forum and found out a restart could help. after doing so, it worked again.
    while i was busy, i also updated the raspi.

we are now 1 week later and it fails again. (offline 3 days ago).
I think with restarting it will be solved, but i want to find out why it is going offline.

I didn’t change anything for months and the configuration ran stable until 3 weeks ago.

what might help:

i saw this last week and now again. it goes off/online, but the last time this is inverted. it goes online first and then offline.

anyone an idea?
already thanks!
