Device appears to be offline after Ubuntu update to 23.10

[MatseB]

Actually I'm not 100% sure that my issue has to do with a recent Ubuntu update (changed from 23.04 to 23.10) but it's most likely. The device (running on Ubuntu 23.10) appears offline for all other devices (currently 5 in total). As far as I can see the Resilio Sync Service is running.

resilio-sync.service - Resilio Sync service
     Loaded: loaded (/usr/lib/systemd/user/resilio-sync.service; enabled; preset: enabled)
     Active: active (running) since Thu 2023-11-09 12:18:33 CET; 16min ago

also it seems that the Device is listening on some Sync relevant ports.

tcp        LISTEN      0           10                      127.0.0.1:8888                   0.0.0.0:*          users:(("rslsync",pid=2280,fd=41))  

tcp        LISTEN      0           10                        0.0.0.0:19808                  0.0.0.0:*          users:(("rslsync",pid=2280,fd=32))

nevertheless I'm also not able to connect to the WebGUI.

Any hints are much appreciated.
