Hello,
this issue is known, we had a quick fix implemented in the code, but currently the quick fix doesnt work. There is a manual way to get by this problem, I will add this to the installation guide within the coming days so stay tuned!
The fix is now added to the installationguide, have fun!
awesome! I will test it monday!
Hello Philipp, so I have tried your fix but it seems that the frontend doesn't connect to the backend. I have started both (frontend & backend) on the same machine. Those are the currently running docker images:

So the backend logs this stuff

After fixing the error as you said the frontend has following logs:

In Chrome it does say that it can't connect to 'ws://localhost:15674/ws'.
Do u have any idea why I get these errors? I followed both installations guides.
If you follow the guide, your containers should look something like this:
The frontend tries to connect to the ports which don't exist since the incorrect containers have been loaded up.
I have cleaned up some mistakes in the Installationguides, I would suggest you try to follow them again, but make sure to delete/shutdown your docker containers before doing so.
Hey Philipp,
thanks for replying so quickly. I have deleted everything and reinstalled the frontend/backend again.
The frontend shows now this:
