Azure for Students verification fails with "You do not have access" and AADSTS50020

I am trying to activate Azure for Students through my verified GitHub Student Developer Pack.

The academic verification step completes successfully, but after submitting the form I receive:

"You do not have access. Sorry but our systems are detecting a problem with your account and are unable to validate your access."

No Azure for Students subscription is created.

When I try to access Azure Portal or Azure Help + Support, I receive:

AADSTS50020: User account from identity provider 'live.com' does not exist in tenant 'Microsoft Services'.

I also tried the Azure Education support route, but it redirects me to Microsoft Engage Center, where I do not have a tenant/workspace.

I have already tried:

• Starting from the GitHub Student Developer Pack Azure offer
• Incognito/private browsing
• Signing out and signing in again
• Repeating academic verification
• Azure Help + Support
• Microsoft Engage Center

My GitHub Student Developer Pack is active and verified.

Could you please review or reset my Azure for Students eligibility/provisioning? I can provide student ID or enrollment proof privately if required.
