Hello brindel.
Please point me to the guide which you used for installation. Also let us know OS version. By the way, was it a ‘clean’ installation? I mean no other apps are installed on the server.

Have same problem.
My installation:
Windows Server 2016, running on a hyper-v host.
Fresh install - noting else on machine.
AD connected.
Installing with domain admin, local admin user.
Trying to install: Onlyoffice workspace community, v 23.05.779
