3.38.1-01 Logviewer doesn't show logs

If we try to view the logs, we can’t see any incoming messages.
However is it stiill possible to view the logs in the Nexus Data Directory
The Loglevel shouldn’t be the problem.
Thanks for your help in advance.

Are there any suspicious errors visible if you tail the logs on the server while trying to view them via the UI? Or perhaps any js console errors in the browser?
