udp6       0      0 :::1716                 :::*                                1000       34359      2260/kdeconnectd

ADDITIONAL INFORMATION
Comment 1 Vlad Adamenko 2022-12-21 00:39:06 UTC 
KDE Connect version: 21.12.3 ( which is latest available in kubuntu repository, but not available in the list to choose from )
Comment 2 Kevin Christmas 2023-01-06 23:41:58 UTC 
I'm observing the same. Also running Kubuntu 22.04.1 LTS

kde-connect version is 21.12.3-0ubuntu1
Comment 3 Kevin Christmas 2023-01-06 23:50:45 UTC 
Running netcat from another machine shows connectivity using IPv4. It's not clear why my phone won't connect and why netstat shows that's only listening to IPv6 ports
Comment 4 ©TriMoon™ 2023-03-15 10:30:53 UTC 
Does your current connection have any IPv4 address configured?
Maybe your DHCP server only assigns an IPv6 address to your connection...
Comment 5 Kevin Christmas 2023-03-15 20:28:22 UTC 
Issue has resolved itself on my machine.

Comment 7 Vlad Adamenko 2023-03-16 20:13:24 UTC 
Yes indeed, i can connect to the port  with nc from the same PC, from other PC in a different subnet, and from Phone.

It's still doesn't explain, why kdeconnect on the phone cannot discover PC, but now, it's different story.

We can close this one.

Will do, I've set it as "not a bug". Hope that's OK.
