Aeon Z-Stick Serial Error


I succesfully implemented two roller shutters (Fibaro Roller Shutter 3). I then removed my Aeon Z-Stick to add some more shutters. After plugging in the stick again, I get the this error message:
OFFLINE - COMMUNICATION_ERROR Serial Error: Port {0} does not exist

When I want to edit the port of the stick, there isnt a dropdown menu anymore. I restarted openhab but still have the same problem. All included devices are offline too.

The logfile looks like this:
