Unable to Register for Microsoft Learn Events?

I am running into an issue across multiple browsers of being unable to register for Microsoft Learning Events.

Most recently today, i am trying to register for the upcoming - https://msevents.microsoft.com/event?id=1787842212

The registration hangs after completing the captcha and then the captcha timesout and the registration is never submitted.

When i tried to click the login on the events page, i get an error - 

AADSTS50011: The redirect URI 'https://msevents.microsoft.com/event'

specified in the request does not match the redirect URIs configured

for the application.

Event ID: 1787842212

Request ID: 50bfa821-6e06-4f00-a27f-4929f843c200

Correlation ID: 10d95455-4537-4f9e-826d-00e9b067bd3b

Timestamp: 2026-07-09T16:40:59Z

Is anyone able to help explain what is going wrong and how i can continue to register for events?
