FYI if anyone has this problem in the future, don’t trust Plex as there seem to be multiple bugs associated with both showing the incorrect IP address as well as when Plex tells you that your server is not accessible via Plex. I only found this out by digging through the forums and found this post where @OttoKerner mentions the bug.
After troubleshooting this for over a week with little help, it turns out I was chasing a ghost that didn’t exist.
