I tried locating the issue in the code, but cannot pinpoint anything.

Hi @nazarewk I was trying to reproduce the issue but not luck. Can you give more information about the version you use and maybe do an additional checks of the /etc/netbird/config.json. Where do you notice that values are reverted to the defaults?

[nazarewk]

It happens when I Connect/login through the UI

Can you make an additional test to prove an assumption.

1. Run netbird down
2. Try to connect via CLI: netbird up --interface-name wt1 --wireguard-port 51840 or any other name/port
3. Check /etc/netbird/config.json
4. Disconnect via UI
5. Connect via UI
6. Check /etc/netbird/config.json

During Slack conversation it was pointed out I was starting without any config whatsoever and neither netbird service up nor netbird-ui support passing the interface/port configuration.

So this is issue caused by #1562
