Through gui I shutted down the service in device Desktop(I wanted to be safe restoring a backup .config/syncthing/* to device Laptop,alltogether syncing with device home-server). Started again syncthing service with
sudo systemctl start firstname.lastname@example.org
then gui was not accesible anymore from 127.0.0.1:8384. Edited ~/.config/syncthing/config.xml replacing 127.0.0.1:8384 with my the actual IP, after that gui was accesible with actualip:8384 but it’s something I don’t support, would like to get it back to 127.0.0.1:8384
Edited again ~/.config/syncthing/config.xml and added 127.0.0.1:8384
In Setings>GUI there is a notification
The GUI address is overridden by startup options. Changes here will not take effect while the override is in place.
