Plex attempting to connect to a device that does not exist

I’m getting the same messages. I’ve never had any device in my network that uses class C network:

You can see that is my Plex Server that is trying to connect to this inexistent IP. I looked up for this IP in Plex files using grep, but I didn’t find anything. I believe this configuation is hardcoded in Plex binaries.

Very annoying!
