I just did a fresh install of UCS, joined it to my windows active directory domain and installed all available updates (4.3-2 errata331). so far everything seemed to work (login with domain credentials to ucs management, list users and groups etc.)
Then I installed nextcloud from the app center
Unfortunately the installer for docker apps seems to ignore proxy settings, but after opening the firewall for the ucs system, the installation went through.
But when I try to logon with my admin account to nextcloud web UI I’m getting an internal server error. “The server was not able to complete you request” (probably an unprecise translation from German to English)
It also says that I should look into the server log. Unfortunately this is my “first contact” with docker and I have no idea where to find it ^^
