Server Version#: 1.24.5.5173
Player Version#: Web
I just got a new server & installed Plex and it was working for around a week before I stopped being able to connect to it locally, but it would connect externally and work normally (with the speed issue) despite being on the same local network & being about to connect to the server through its IP. The server is running within Docker on unraid using the official docker image.
