Firestick 4K Max spamming connections

[jcdick]

My folks have a Firestick 4K Max and it seems to be spamming connections to my JF server.  Every couple of minutes, the Activity Log shows a SessionStarted entry from their device that only lasts a second or two, followed by the expected SessionEnded.  I'm just curious if anyone else has seen this behavior.  They are running 0.18.2

Thanks.
