I have made a huge change to my home network, and the OS has pulled a NEW IP from my router. How ever, syncthing tries to start and fails because its still listening on the OLD IP that no longer exists on my router AT ALL. Any ideas how to change that?

My GUI listen address is: 127.0.0.1:8384 which works fine (I would not expect “:8384” to work).
Please also check the connections tab (settings area) to ensure you have not manually bound syncthing to the old IP that way.
Finally, the error message indicates a specific issue – whatever launches syncthing on your ubuntu is passing startup options (which probably include the old IP), which are overriding the GUI. I would resolve that first.
:8384 is equivalent to
0.0.0.0:8384 and means listen on all addresses.

There’s also the sync port listening address which may have been changed. It should usually be set to
