X50 Teams Mode: White screen with about 75% progress and message displaying "Signing in," but does not go beyond that.


Expected Result: While in Teams Mode the account to stay signed in all the time.

Actual Result: Codec goes into white screen with progress around 75% with message displaying “signing in,” but it does not go past that.

Interop Environment

Call server platform and version: Microsoft Teams version 1449/1.0.96.2020102101

Ecosystem type:  X50 in Teams Mode >> system.ecomode.activeapp="Teams"  /* CacheOnly */

Provisioning service: None

Additional products or hardware:

Video hardware affected or included (specific models and software versions required):

• Studio X50 @ SW version 3.3.0-282003


    Teams account is signed in and working fine. It can work for a day or half a day and then it goes into the signing in state. Hard or Soft rebooting the codec does help.


    Work around is to switch provider to Poly and then back to Teams. At this point account can register and all works fine. Until it fails again.


Log Work:  

    The logs show the reboot and according to customer this was right after they tried to sign in:
