After I installed ssh server on KDE Neon computer, KDE Connect stopped working and cannot find Available devices even though my device was connected before ssh server was installed. I removed and re-installed the App from KDE Neon via Discover store but still KDE Connect not showing any available devices on KDE Neon and on Android App. STEPS TO REPRODUCE 1. install ssh server with command: sudo apt install openssh-server -y 2. Run KDE Connect application 3. No Available devices found OBSERVED RESULT After installing openssh server, No devices are available to connect on KDE Neon and Android app EXPECTED RESULT After installing openssh server on KDE Neon, KDE keeps working. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE NEON (available in About System) KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.101.0 Qt Version: 5.15.7
I also tried "Add device by IP" on KDE Connect Android app to no avail - I entered the IP address of my KDE Neon computer (they are both in the same network without firewall)
Resolved! One of the steps of installing ssh-server was to allow port for ssh with (I supposed this created the issue) sudo ufw allow ssh sudo ufw enable && sudo ufw reload I followed the guide to troubleshoot on section "I have two devices running KDE Connect on the same network, but they can't see each other" at https://userbase.kde.org/KDEConnect#Running_KDE_Connect_over_OpenVPN sudo netstat -tunelp | grep -i kdeconnect # process was connected netcat -z -v <your-phones-ip> 1714-1764 # Connection was refused on all ports I then opened firewall ports manually and I got connection back sudo ufw allow 1714:1764/udp sudo ufw allow 1714:1764/tcp sudo ufw reload Although the issue is now resolved I will leave the issue open to have someone take a look because I believe the issue could have been avoided if the re-installation of the KDE Connect Neon App had taken care of the firewall rules during the installation process.
