Comment 5 for bug 1871030

For what it's worth, the "IPv6 only" comment above came from a misunderstanding of the netstat output. If it lists a service listening on "tcp6", it is _also_ listening on IPv4. Confirmation by:

    root@testbox:~# nc -v 127.0.0.1 1716
    Connection to 127.0.0.1 1716 port [tcp/*] succeeded!
    ^C

    root@testbox:~# pkill kdeconnectd

    root@testbox:~# nc -v 127.0.0.1 1716
    nc: connect to 127.0.0.1 port 1716 (tcp) failed: Connection refused

So, the KDE Connect has an open port on both IPv4 and IPv6
