Original GitHub issue: https://github.com/hirschmann/nbfc/issues/1113

Describe the bug
When running any command, nbfc just returns Connection refused. Tried with both sudo and no sudo. nbfc.service is definitely enabled and up, since service nbfc status shows it as running. Restarting the service with systemd does nothing, but starting the service manually with nbfcservice.sh does, and after that, nbfc works like it should. What's weird is that if you kill nbfc using sudo killall mono, then restart the systemd service, nbfc will keep working normally.

To Reproduce

Install nbfc on Ubuntu 20.04 following the instructions from the Wiki
Run nbfc, get Connection refused

Expected behavior
It should work 🤷🏻‍♂️

System information
Lenovo ThinkPad T490s
Ubuntu 20.04.02 LTS
NBFC 1.6.3.0
Mono 6.12.0.122
Log: https://hatebin.com/dvepjwtwpq
Systemd log: https://hatebin.com/upndtobjqv

Additional context
I'm using a slightly modified version of the T430s config, but this isn't the problem because the other ThinkPad configs result in the same issue.

There's been a few issues about the same thing but none of the solutions there fixed anything.

Can you show me the output of ls -la /opt/nbfc ?

Weirdly, since I updated to 21.04, I can't reproduce the issue myself anymore. Close?
