small thing. On a fresh install and nothing done so far the GUI looks like this:

Pressing now on the red cross button "Delete tunnel", results in:

{"level":"debug","time":"2023-09-29T07:31:14+02:00","message":"Settings init"}
{"level":"debug","time":"2023-09-29T07:31:14+02:00","message":"loading settings"}
{"level":"debug","time":"2023-09-29T07:31:14+02:00","message":"settings file doesnt exist"}
