Two questions: Which version of KIO are you running? And, this may sound weird but could explain the issue, are you running Spotify on your phone?

[IP-] [ ] kde-frameworks/kio-5.43.0-r1:5/5.43 > And, this may sound weird but could explain the issue, are you running > Spotify on your phone? Yes, although Spotify is usually idle while I'm at home. I mostly use it via bluetooth in the car. I cannot really explain the issue, it just crashes. I don't even notice it (except there are no longer any notifications). I usually only detect this when looking at dmesg.
I have the same issue (fedora 27) but have no idea what causes the problem either. Its been fine all day today. I don't have Spotify but there maybe a possible connection with WhatsApp notifications maybe. It will just crash and the plasmoid then shows "no devices available" I then check dmesg and it shows this: kdeconnectd[1585]: segfault at 10 ip 00007fd83834aa08 sp 00007ffce8da9540 error 4 in kdeconnect_notifications.so[7fd838344000+15000] Running frameworks 5.44, but I have seen this for a few frameworks versions now.
