Octopi internal server error

After connecting the raspberry pi 4 to my ender 3 pro via USB to Micro USB cable, the octopi webinterface is no longer reachable due to Internal Server error

What did you already try to solve it?

Reinstalling octopi, reintegrating the pi into my network

Have you tried running in safe mode?

Additional information about your setup
