OneDrive Business Account can't connect (0x8004e4c3)

Question

Since yesterday, seemingly out of the blue, my OneDrive Business accounts stopped syncing on both my PC and my Laptop. After signing out I cannot sign back in and get the error code 0x8004e4c3, and the error no network connection [2603].

I'm using Windows 11 Build 22000.795 and the latest OneDrive version.

Same problem as here:

Clearing the cache and reinstalling OneDrive didn't help. Neither did disabling the firewall or my windows defender. Again, I could connect to my personal account but not to the institutional account.

TLS 1.0, 1.1, 1.2, and 1.3 are enabled. Still doesn't work.

Any help would be much appreciated, my workflow is currently majorly impaired.

Hello Paul,

No, everything works fine on another computer.
