Is Business Central Somehow "Down"?

Hi:

All day today, I have been having issues getting into Business Central.

And, when I can get in, it has been very slow.

I have at least two separate Azure Active Directory accounts for two separate Business Central tenants.

As of now, I can't get into either one.

When I try Multi Factor Authentication, the screen freezes and eventually shows this message:

AADSTS900561: The endpoint only accepts POST requests. Received a GET request.

Is Business Central down, across the board?

Hi, I just tried it and it works fine. You can try updating the Authenticator app on your phone.

There is an active known issue about BC performance. It could be related for that.

A fix is being rolled out globally.

Hi:

I just learned that internet service in this area was spotty, yesterday, and it has been restored.

BC is working very well, now, as it always has. :)

I apologize, for the bother.

Hi

Clear browser cache or try a different browser/incognito mode.

Ensure the login URLs are correct for each tenant.

Try logging in using Microsoft Authenticator app instead of browser-based MFA.

If the problem persists, contact your Azure AD or Business Central administrator to check MFA settings and authentication endpoints for your tenants.
