There are many posts in this forum you can search for (also on the nextcloud or owncloud forums- as this is no univention symptom)
For quick help -
The Problem is the FQDN you are accessing nextcloud- this has to be added to the config file -which is also stated in the popup you posted here

Eh

p.s. Be aware you have to use occ command line Tool inside the nextcloud docker container as editing the config file per editor is not allowed at Nextcloud/owncloud since a long time
