Unable to Sign In - MVP Program Hub

When I sign in, the page seems to load with a spinning popup bar. However, after a while, I get the message:

"We couldn't sign you in. Please try again."

I have tried the following steps, but nothing worked:

• Clearing the cache
• Using an incognito tab
• Changing my password

As a result, I cannot access the MVP Summit Scholarship page or the FAQ page, which is frustrating since I need the information. Could you please help me on that? Thanks in advance.
