Server not accessible from Android TV

Server Version#: 1.42.2.10156
Player Version#: Latest Android TV version available in the appstore

Since like a week ago, my server has started to not be discoverable by the Android TV app. This applies both locally, with my TV, as well as in 2 other remote locations, both also running android tv.

At [random] times, the server/libraries are discoverable again, can be pinned again and media can be displayed as well. However, at a later stage in the day, the library is not discoverable again and the server is not displayed at all (the “+ Your media” button shows instructions on how to get access to a server, like the accounts would have no access).
The server is definitely discoverable. Opening the web app, or the iOS app from the same network, everything works just fine. It’s just the Android TV app that does not sees it. Restarts of the docker container does not seem to do much, sometimes the server becomes discoverable again for a brief period by the android tv app, but it’s so inconsistent that I think it’s more of a coincidence.

And yes, remote access is enabled, port is forwarded (again, other apps like web or ios can access the server just fine).

For now, I had to switch both my 2 friends and my TV to a 3rd party (competitor) app.

I would like to identify and fix the issue, so that at least I can switch my TV back to the plex app.

Up, 3 months later this is still a problem. Libraries from the server (and the server entirely) keep disappearing from the android TV app. Everything works fine in a browser.

The only way I found for this to be temporarily fixed is by toggling the remote access off and on from plex.tv server settings (under Remote access). However this fixes it only temporarily and it breaks again in a few days. I can’t be doing this all the time when family members reports problems with it.

Note: the server is properly port forwarded AND the location has a public static IP.

Also, it cannot be that I’m paying for a service (plex pass) and literally no one from Plex has looked on this complaint for a few months now. Am I on the wrong support channel?

Android TV is the only way I’m using the plex app and without it working for me it is a full disruption of service.

Plex Pass is a license to operate the server with additional features not a support license. With the 10 or so of these types of posts a day it is requested that you include your server debug logs to avoid playing 20 questions.

In 99% of cases it is a local configuration issue.
Is your Docker in host mode?
Is your router and all your devices pointing to 1.1.1.1 or 8.8.8.8 for DNS?
Do you have any type of Ad block running?
On the Server Settings > Network page, have you entered any custom information into the blank fields?

etc.
