Steps to reproduce

Wait till session expires
Press reload
Check logs

Expected/Desired Behavior

It looks like session handling issue in the application. Probably CloudBeaver is trying to find web sessions which after reload is not exist.

CloudBeaver Version

25.1.0

Additional context

CloudBeaver is running in Kubernetes environment.

Hi @jonsbun
CloudBeaver is gradually migrating different parts of the application to use WebSockets. This issue can be helpful.

I ran into this issue as well when using Safari during initial configuration. It seems to work fine with Firefox. YMMV of course.

Other issues with safari include "Project is not found" when navigating the ui. Safari Version 18.5 (20621.2.5.11.8)

Are you still experiencing any difficulties?
We have added some info about websockets to the wiki.
