Bug description

After Upgrading Nextcloud (docker) to version 28 (currently 28.0.1) onlyoffice stopped working. Setting do look okay and show me all the options for onlyoffice. On v 27 it was working fine. When I try to open a file it shown me "Onlyoffice is currently not available. Please contact a system administrator."

I use the integrated "ONLYOFFE" App v9.0.0
and App "Community Document Server" v0.1.13

Log error see below.

Steps to reproduce

1. Setup with NC 28, ONLYOFFICE APP and Document Communitiy Server App
2. Try to open a file that opens in onlyoffe
3. Error message is displayed and I see the reported error in the log.

Expected behavior

It should work :-)
