Snippet from logs (getting flooded) whenever I watch anything (I removed my IP even though its local internal IP (habit) but why does the logs say (WAN). Nothing appears to be wrong from stance of videos play fine, no transcoding, all local as reported by dashboard and Tautulli for the connection while playing again no playback issues. I just noticed when looking at other things and tweaking the logs fill with this error constantly during playback. Wanted to know how to get rid of it. I tried multiple different setting options and nothing seemed to change. I even loaded my wildcard certificate from LetsEncrypt for my domain, didnt matter with or without in settings.
