OMS | Log Analytics : The WWW-authenticate header doesn't contain a valid authorization

Hi eswar_chandra,

It seems you are not alone with this issue. I see two users report the same issue and the Brian_Wren already notice this issue, you can see: https://docs.microsoft.com/en-us/azure/log-analytics/log-analytics-powerbi

You can keep an eye on the update in that document by Brian_Wren. Also I will try to reach Brian_Wren to find what is happening. 

Best Regards,
