Editor updated notification

[king-anduin]

Hi, I recently updated my NC19 to NC20. Everything is working properly except the fact that OnlyOffice does not open any files. It creates them. That’s it. Existing files or new created files can not be edited.

I get this notification. Afterwards OnlyOffice is doing nothing. Just loading screen. No trace of a error in my log files. I tried to reinstall both. OnlyOffice and documentenserver but it's still the same error. I hope someone can help me out here.
