I am trying to set up KDE Connect between a machine running Linux Mint and my Android-device. It does not show up, and it turns out I don’t receive any response if I ping it, and I have the same issue trying to ping the machine from my Android device (from Termux). I’ve tried two different Android devices, but no luck.
This is not an issue with two other machines I have. Both have KDE Connect setup and I can ping the phone just fine, and I can also ping from the phone. They’re all connected to the same VLAN. I can also ping from this machine to the other machines. ufw is disabled.
What could be the issue here?
EDIT: Connection established suddenly after installing and running iptraf.
I fixed this on my EndeavourOS machine by enabling kdeconnect in the firewall settings.
ufw is disabled, so it shouldn’t matter if it is set up or not, right? As far as I can tell I don’t have any other firewall software running - I’ve not installed anything, so it would be the default Linux Mint-stuff that I would have installed and enabled in that case.
