I’ve ran into the same issue. My setup is Unraid server >> hardware firewall >> ISP fiber gateway (set in bypass). My Unraid server has a public IP address. No changes have been made to the server. I have a CNAME setup in Cloudflare pointing to my domain (plex.mydomain.org) and a reverse proxy configured as well. This has been working for the past 2 years.
That said, if I access the local Plex web gui (http://192.X.X.X:32400/web), my libraries/content are available. As soon as I try to access my Plex server via the web (either via public IP address:32400/web or through DNS plex.mydomain.org), my content is not available. When I go to “More” >> “Your Media” I get the “Add your media to Plex” page, as if it is not detecting my server.
Is this a DNS issue similar to what happened a couple of years ago (Cant connect to Plex outside local network - #128 by ChuckPa)?
Under Remote Access, it says “Fully accessible outside your network” unless I check the “manually specify the public port” of 32400… then it fails. Verified the port is accessible via my public IP address
