firewalld kdeconnect configurations
SUMMARY
Haven't been able to connect any devices via kdeconnect, either via bluetooth
or wi-fi. Followed the steps in the troubleshooting page of the KDEconnect wiki
to no results.
I use KDEneon and firewalld (v2.1.1) has the proper port exceptions.
Output of netcat -z -v <my-phone-ip> 1714-1716
Connection to <myphoneip> 1716 port [tcp/*] succeeded!
Output of netstat -tunelp | grep -i kdeconnect
