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.
With your EDIT my first thought was “Have you tried turning it off and on again?”.
Hehe yeah, this persisted over several days and through several reboots and on two different phones. No clue what changed as I understood iptraf to simply help me diagnose. But a run directly before and after running iptraf for the first time had different results, and now I am reproducing it every time.
Which version of KDEConnect do you run in Linux Mint? Seems like they package an old version from what I gather when searching for answers:

https://old.reddit.com/r/linux/comments/1b5fvay/how_do_users_of_mint_or_other_debianbased_distros/
Are your other machines running distros with more up to date repositories?
I’ll look closer into this when I’m back at the computer in about an hour. In the post on the KDE forum, they seem to get an error complaining about the version though, while in my case they don’t show up at all when I attempt to pair. I’ve checked the things listed on the KDE Connect wiki, but those checks pass.
EDIT: UDP discovery was turned off on my phone, and turning it on allowed connection. All is good now!
