UCS - Univention Corporate Server
#1

I have upgrade owncloud app from version “10.12.1” to “10.13.1” from univention.

univention-app info
UCS: 5.0-5 errata829
Installed: letsencrypt=2.0.0-2 owncloud=10.13.1
Upgradable:

After upgrade i had one error before this one, i was unable to access owncloud with this problem:
Error: “You are accessing the server from an untrusted domain.”
Solution: Run this command “univention-app configure owncloud --set OWNCLOUD_TRUSTED_DOMAINS=xyx.domain.com”
Link: https://help.univention.com/t/owncloud-you-are-accessing-the-server-through-an-untrusted-domain/21687/6

Now i can access but gives allways the following error/info message:
