On your Ultra service, Plex Media Server requires the secure connection to be at least set to Preferred in Plex Media Server settings, or you will face the error "Can't connect securely".

Plex Media Server is a proprietary media player suite that organizes video, audio, and photos from a user's media collection and online services. The user can access and stream the content from the server to any device where Plex is offered.

More information can be found here.

In this section, we will be detailing the initial configuration of your Plex Media Server. This assumes that you have stored your media in ~/media. Our Plex installation automatically creates your media folders inside ~/media as follows: ~/media/Movies ~/media/TV\Shows ~/media/Music

No further step needed, although if you would want to change your library paths in Plex, you can read a guide about it here.


Initial UCP Configuration

Like all applications, Plex Media Server can be installed from the UCP, this application, however, has one extra step. When you click on Install and are prompted with this screen, you will need to visit

If you have not done so already, sign in to your Plex account and copy the claim code provided. Paste this into the prompt and then click Install.

Your Plex Media Server comes configured out of the box. Just connect to your Plex Media Server instance by following the link in the UCP - as is typical with all official applications.

Troubleshooting Information

How do I update Plex?

Our Upgrade/Repair Plex image is locked to a version/image that we have deemed to be stable on our infrastructure. The newest version is not always the best version, as Plex has a track record of deploying new releases with a lot of bugs.

To upgrade to the latest Plex version, you can do this via SSH. Instructions on how to upgrade can be found here.

My Plex is down. What are some troubleshooting steps to resolve it?

Usual causes of this are Plex updates, or the server cannot read or write to the library, which is a common occurrence with Rclone mounts. In these cases, the RAM usage of Plex would go up, and the system will kill your Plex instance.

It is also worth noting that some of Plex's features, especially logins, server claiming API, and web apps, are centrally hosted by Plex and not locally attached to your Plex Media Server. Any outage announcements will be posted here:

ps aux | grep [p]lex
cat .config/plex/Library/Application\ Support/Plex\ Media\ Server/Logs/Plex\ Media\ Server.log
mv ~/.config/plex ~/.config/plex.bak
Why is Plex producing a transcoder error?

The Plex Transcoder exited error is a general error for not playing back the media using the video player or transcoder, and you may need to view the logs. You can either run the following command on SSH and look for any errors. You can also download the logs from the settings in the Plex webUI.

cat .config/plex/Library/Application\ Support/Plex\ Media\ Server/Logs/Plex\ Media\ Server.log
ERROR - An error occurred reading the file

If you encounter the following error message: ERROR - ERROR - An error occurred reading the file: /homeXX/username/SOMEMOUNT/path/to/File.mp4 (5)

Something is wrong with your Rclone mount, and it will need to be investigated separately. In this case, it is usually Error 403: Rate Limit Exceeded, rateLimitExceeded, or a wholly dropped mount endpoint.
