Hello @Cynthia Mitchell,
Thank you for posting your query on Microsoft Q&A.
Based on your description, I understand that you've encountered an error message while accessing the Azure Portal. To better understand the issue, could you let me know if the error occurs every time you access the portal? Is the issue still persisting, and is it affecting only you or other users in your tenant as well?
Please share these details to help us diagnose the issue more effectively.
As an alternative, I recommend trying to log in to the Azure Portal by directly targeting your tenant ID or domain name. You can do this by navigating to:
portal.azure.com/<TenantID> or portal.azure.com/contoso.com (replace "contoso.com" with your domain name).
Thanks,
Raja Pothuraju.
