How is this STILL an issue?
Now I remember why I never update PMS and why I ran 1.14 for over a year.
This is definitely an issue on the Plex side. I have had remote access configured for 3+ years and never had an issue. My port forward is still active, as are all of the other port forwards I have configured on my router. I can see the plex.tv URLs from this list(https://s3-eu-west-1.amazonaws.com/plex-sidekiq-servers-list/sidekiqIPs.txt) being let through my firewall and directed to my Plex Media Server’s internal IP address, on port 32400.
Following the steps in this post - Remote access failure I can see all of my server URLs that are being published to plex.tv. I select the one that contains my external IP address and connect to it on a remote network JUST FINE. Yet Plex continues to tell me that my server is not accessible remotely & my users can not stream.
