Roku Plex App Thinks PMS Is Offline

I have a PMS running on KDE Neon (Kubuntu essentially) and my Roku 4800 Plex app has thought my PMS is offline for weeks now. I have tried removing the plex app, restart the roku and reinstall and it still doesnt work. Plex app still works fine on Apple TV 4k, Sony TV and Chromecast with Google TV. It is just the Roku 4800 that can’t seem to see the server.

Any suggestions on how to fix or further troubleshoot this?

Thank you.

I also tested my Roku 4660 and it has the exact same issue.

The roku logs should hopefully have info on how it is trying to connect.
