Fully accessible outside your network BUT

Anyone with an issue with remote access whilst running on 1.13.8.5395 please provide logs / screenshots. An issue was fixed earlier today on plex.tv to do with detection of the public IP of the server - where it was leading to an IP address such as 172.17.0.1 being seen as the public ip

If any one had that issue, please disable / re-enable remote access or restart the server and ensure remote access is enabled

For any remaining issues, ensure

Please make sure you run on the 1.13.8 release and have debug logging enabled - see https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/

Then restart the server and if remote access is enabled but failing, capture screenshot and logs zip and attach
