after grommunio-office update from v7.4.1 -> v9.4.0 it stopped working.
at the same time grommunio-files was updated from v31.0.13 -> v32.0.12.
when trying to open an office document I just get the message
"ONLYOFFICE is unavailable. Please contact your administrator."
tried re-saving the onlyoffice settings. URLs are correct.
ds-docservice and ds-converter services are running.
I can see nothing special in the files protocol or in journalctl.
I have the exact same problem on 3 servers.
Any ideas how to debug this?
