Collabora Probleme

Hello,

i have used Collabora for many Months. Yesterday i disable it and would try Onlyoffice. But now i would go back. But i have no access to the documents. Only the connecting circle works.

My Setup:
Nextcloud 11.0.3 on https://cloud.domain.tld
Collabora latest docker image connected with cloud.domain.tld
connection to office over docs.domain.tld

docker logs say me this:

did you try to update the dockercontainer since then, or apply that fix?:
