Unable to delete a user – RemoteServiceUnavailableException

[Juanrendon 4]

Hi,

I'm having an issue with Emby when trying to delete a user.

Whenever I try to delete the user, Emby shows the following error:

Exception of type 'MediaBrowser.Common.Extensions.RemoteServiceUnavailableException' was thrown.

Because of this error, I'm unable to delete the user.

Has anyone experienced this issue before or knows how to fix it?

Any help would be greatly appreciated.

Thank you!

Emby Server version: 4.8.10.0
Operating system: Linux (Ubuntu 22.04, kernel 5.15.0-130-generic)
.NET Runtime: 6.0.31
Installation type: Native .deb package

Issue:
I'm unable to delete certain users from the web dashboard. The following error is logged when the delete request fails:

System.ArgumentNullException: System.ArgumentNullException: Value cannot be null. (Parameter 'ConnectServerId')

OK I would suggest updating to Emby Server 4.9 or later.

[Juanrendon 4]

I currently have Emby Server 4.8.10.0 installed on Ubuntu 22.04 as a native .deb package.
I plan to download version 4.9.5.0 using:

wget https://github.com/MediaBrowser/Emby.Releases/releases/download/4.9.5.0/emby-server-deb_4.9.5.0_amd64.deb
 

After downloading the .deb, should I simply run:

sudo dpkg -i emby-server-deb_4.9.5.0_amd64.deb

to upgrade the existing installation?

[Luke 43148]

Yes.

[Juanrendon 4]

Thanks! With the new version 4.9.5.0, I can now delete users successfully, so that issue is resolved.

However, I still cannot create new users using Emby Connect. I get this error:

“Error adding Emby Connect account. Have you already created an Emby account? Register at https://emby.media/connect.”

So the problem is now only with adding/creating users through Emby Connect.

Any idea what could be causing this issue or what I should check?

[Luke 43148]

Has an account been created for the email address that you're trying to add?

[Juanrendon 4]

Yes, of course; in fact, if I try to create the user on another server, it works fine. But on this one, that error appears. I'm not sure if the issue lies with my server or with a corrupted installation file.

Hi.  Did you clone or restore this server from another one?

[Juanrendon 4]

That's right; I cloned this server from another one—something I've done before without issues—and you just have to delete the files

rm connect.txt
rm device.txt

before starting Emby, and it works perfectly.

However, I did the same thing with this server; everything was fine at first, but over time, these problems started to appear.

[ebr 16812]

Try shutting down the server and removing device.txt again.  This will cause you to need to re-connect any Connect accounts.

[Juanrendon 4]

I just did that, and now things are worse; it won't accept my Emby Premiere key—it just keeps spinning.

[Juanrendon 4]

I see that the rm connect.txt file is missing from this server.

Check firewall and network permissions.  That may be your problem all along because Connect isn't going to work if the server can't get out to the internet.

This will help:
