and if send this command: sudo docker ps

There is no EGroupware. Therefore it cannot be reached by the reverse proxy either.

We had such a case (in German):

System läuft nicht mehr nach Update mit docker

[andrea.soc]

before the update, i read the notes and i think that’s the point but i don’t know how to tell it to use apache instead of nginx

[andrea.soc]

i revert the server to 19.1 an retry the upgrade and i noticed this error:

Solved.
Was a problem of Internet connection of Server of MTU, solved on firewall of Internet connection.
