**Description**  
In zoom windows sdk , on ZoomController::sdk\_authenticate we were repeatedly getting - Authentication failed with AuthResult = 9. This AuthResult corresponds to ` AUTHRET_NETWORKISSUE - Network issues.` It occurred from [2021-10-18 17:06:02.309237 UTC] to [2021-10-18 17:33:27.397556 UTC] ~ for around 30 mins. The issue resolved on it’s own after that. Please help us know the RCA.

**Which Windows Meeting SDK version?**  
v4.6.21666.0428

Hey @satyam.gupta,

Thanks for using the dev forum!

This was likely caused by a backend issue. Please let us know if you see this happen again.
