Description Aleksandar 2025-11-10 15:03:14 UTC
SUMMARY
From a few days ago my phone is no longer reachable from my PC when using either wired internet or wifi. Enabling MDNS in the android app fixes this issue, but is marked as deprecated.

STEPS TO REPRODUCE
1. Install kdeconnect on phone and computer
2. Pairing fails to find devices

OBSERVED RESULT
The phone cannot see my PC and my PC cannot see my phone. Using "Add devices by IP" works but this is not a great solution since i use a laptop and the IP changes switching from wifi to dock to built in ethernet port.

EXPECTED RESULT
Phone and PC should see eachother in the pairing menu

SOFTWARE/OS VERSIONS
Linux: Fedora Workstation 43
Kdeconnect version: 25.08.2 (fedora repos)

same issue here. I updated the kdeconnect app on my phone from F-droid today. Version 1.34.3
I use 25.08.3-1 from the Arch repos on the PC
Comment 2 Sander 2025-11-22 10:45:56 UTC
Same issue for me.

Versions:
KDE Connect (Android): 1.34.4
KDE Connect (Fedora RPMs): 25.08.2

Additionally to the observed result from the report, this also happens:
Already paired devices do not connect automatically to each other while being to the same network (OpenVPN network with client-to-client connections allowed).
Sometimes they do connect when I manually click refresh in both the KDE Connect Android app and on the other device (my desktop PC running Fedora/KDE), but that does not always work. And when the connection gets lost, it also does not reconnect.
I have also tried using LAN/WiFi to connect my phone to my desktop (and completely disabling my OpenVPN setup, to ensure that is not the cause of the connection problems), but then the same issue still appears.

My configuration:
All the devices that connect with my Android phone have this problem.
I have added all my devices by IP (actually hostname) like this:
* <phone hostname>
* <phone hostname>.local
* <desktop hostname>
* <desktop hostname>.local
* etc.

The MDNS setting was turned off (with message that it is being reprecated and I should report a bug if I KDE Connect only works when the setting is enabled).
I enabled the MDNS setting, and all connections went away immediately. All devices now connect again to each other. Both on LAN/WiFi and using my OpenVPN setup.
