All of my remote users are having issues with connecting to my Emby server.
This all started after I realized I had my Emby server exposed on both ports 8920 & 8096. I immediately removed port 8096 and confirmed the Emby iOS app was working for me outside my environment. In fairness I did have issues connecting remotely at first however, I was able to remove my server and add it back using the FDQN and I was able to connect no problem. Both locally and remote. Since I've noticed that one of my users hasn't connected in 3-4 days, I reached out and realized they were having connectivity issues. They are also using the ios app but never get the option to delete the server and re-add but rather get prompted that the connection has timed out. I do have an SSL certificate on a properly configured FDQN, I checked the server settings but seeing as the end user device isn't able to connect the server never sees the connection.
I've done some light searching online but I can't find any instructions that would help me guide my iOS users on how to reset the Emby iOS app or how to delete and change the server. Things happen that will sometimes make the Emby server inaccessible so I'm sure there must be a way for my remote users to regain access without having to re-open port 8096. I originally suggested they delete the app and re-add it however, I thought placing the device in Airplane mode would cause it to fail and prompt to remove the server. Of course, that didn't happen but I never asked them to delete the app and re-add. Would that work? I figured the device would retain the settings even after the app has been removed.
