(solved) Jellyfin spamming an external IP?

[Strangle7068]

I was digging into logs to troubleshoot a library that will not play but discovered Jellyfin is, I think, trying to call out to an external IP every .2 seconds and has been for days, the connection is refused. and then repeat,

first is this Jellyfin calling out or is this someone else calling in?

and more importntly why and how do I stop it?

there are thousands of these, all the same except for the time stamp:
