Hi,

we are getting error from yesterday when we try to connect to Azure Portal "https://manage.windowsazure.com"
We cannot login in the administration panel (where all service, web sites, database are listed) and we get a general error page while on the address bar I get this "https://manage.windowsazure.com/Error/Login?issueType=StsCertificate"

We tried on several computers with different browsers. 
We have cancelled browser cache data and cookies and also update the PowerShell.

What we have to do to get in again?

Thanks,
Best regards

Where are you located ?

Can you login to the New Azure portal https://Portal.azure.com

Hi,

 What is the Error message you are seeing in the Browser window. Portal Login issues sometimes gets resolved automatically after some time, Are you able to Login now?
 Are you able to Login to the New Preview Portal (portal.azure.com)
 Since you have already tried most troubleshooting steps, You can contact Azure Support with a free Billing Ticket and they will check for any issues for your subscription from the backend.
