Logged out of web UI (mb3admin.com Error)

[Trunk 21]

Emby Server: v4.2.1.0

When trying to open the web UI I'm automatically logged out. It do not remember me anymore (started a few minutes ago). Checking the dev console i see this error:

HTTP400: BAD REQUEST - The request could not be processed by the server due to invalid syntax.
(Fetch)POST - https://mb3admin.com/admin/service/registration/validateDevice?[longDeviceId-and-stuff]

Any idea?

 

PS: The login screen display a "Get Emby Premiere" button also now (I do have lifetime license). It's not hidden probably due to the error.

Are you clearing browsing data?

Are you clearing browsing data?

 

I'm not clearing any cache or cookies.

 

Just did some testing and the same happens in Edge, Chrome, Edge (Chromium) and Firefox. Same error in the dev console.

 

I'm able to log in. But if I reload the page I'm sent to the login page again.

I'm not able to reproduce. Generally this will only happen if browsing data is being cleared, or you're in incognito mode.

It's definitely on my side, locally. Some glitch somewhere. After rebooting my PCs it only occur on one of them now.
