SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.80
KDE Frameworks Version: 6.13.0
Qt Version: 6.8.2
Kernel Version: 6.13.9-200.fc41.x86_64 (64-bit)

ADDITIONAL INFORMATION
Firewall is off. Both devices are on the same wireless network.
If it's relevant, the phone is still running Android 12 (it's ineligible for
further updates).
Here's the debug logging from kdeconnectd on the host when this happens:
kdeconnect.core: Discarding second UPD packet from the same device
"a0a12727_d195_401b_a42e_5998e383fb12" received too quickly
kdeconnect.core: TCP connection done (i'm the existing device)
kdeconnect.core: Starting server ssl (I'm the client TCP socket)
kdeconnect.core: Ignoring self-signed cert error

The same thing happens in reverse if I try to pair from the KCM: when I open
the Android app, the phone briefly appears and then disappears.
This has been going on for months and I'm only just reporting it now.
