Auto updater didn't work for update version 1.43.0.10492

[rvass]

Had to update manually.

Do you have the updater logs for that update? My server updated to that version without issue.

Here are the logs for the important bit:

2026-02-28 07:47:51 Current version: 1.42.2.10156.

I can confirm i ran the executable as administrator. Any ideas what would be causing this?

[TechieGuy12]

The unauthorized messages are coming from the attempts to get the current play/recording count. The issue is usually related to the incorrect Plex token being sent to the Plex API. The play/recording counts are being requested to determine if anything is being played or recorded before attempting to update Plex.

The updater looks to the Windows registry to get the token for Plex. The path it looks for the token is HKEY_CURRENT_USER\SOFTWARE\Plex, Inc.\Plex Media Server and is the data of the PlexOnlineToken value. If the updater is running under a user ID that has an incorrect token in that registry value, then it will fail when sending an API request to Plex.

When you run as an administrator, that account may have the correct token in the registry (as the token is in the registry location specific to the user), so it works.

So how do i resolve the issue? Btw my user account does have admin priveleges.

[rvass]

The service log on account was set to Local system account. I have changed to my user admin account.

Is there a way that i can test it?

[TechieGuy12]

That service is managed by Plex and should remain running from the Local System account.

This Plex updater should run as a scheduled task periodically. From the scheduled task, you would set the ID to run under as the ID you are running Plex with.

For example, the Plex updater runs every morning at 4am on my server.

I use the following action settings:

Program/script: <path to the updater>\psupdate.exe
Arguments: -silent -log <path to the log folder>
Start in: <path to the updater>

Replace <path to the updater> with the full path to where the updater is located on your server, and also the <path to the log folder> with the full path to the folder where you would like the updater logs to be stored.

Thanks I didn't realise the scheduled task was required for automating it. I was following the Plexopedia article and there was no mention of that there.

Anywho, unfortunately i am still getting the same unauthorised error even when i run it manually by right clicking the installer and select run as administrator. (I think you might have misunderstood me when i said i had to update it manually. I didn't mean manual through your executable, i meant updated through the Plex server web app.)

Double clicking on the executable produces this:

and right clicking your exectuable and selecting "run as administrator" produces the unauthorised log output:

If the ID you are using is an admin and it is also the one that runs Plex, then you just need to create a scheduled task that runs with that ID.

The output you showed running the app looks good.

[rvass]

Okay I have created a scheduled task now so we'll wait and see when the next server update is released. Although i'm still a bit concerned that i see the "The connection to the Plex server wasn't successful. Status: Unauthorized." log when i run psupdate.exe manually as admin.

[rvass]

PmsService is running with same admin account
