Multiple Azure alerts: Experiencing authentication issues

Paul Bourmatnov 1 Reputation point

I just signed up for a subscription with my email that has an azure account already. I am getting this alert every minute. Any ideas what may be causing it? I am not attempting to do anything at this point but am being flooded with warnings.

Experiencing authentication issues The portal is having issues getting an authentication token. The experience rendered may be degraded. Additional information from the call to get a token: Extension: Microsoft_Azure_ActivityLog Resource: microsoft.graph Details: AADSTS50013: Assertion failed signature validation. [Reason - The key was not found., Thumbprint of key used by client: Thanks, Paul

    Everyone who are having azure account and subscriptions, is getting those alerts. No mistake at your end

    There was an outage with authentication service which impacted Microsoft services including MS Teams..

    You might get few more alerts until issue is resolved.
