Microsoft Learn for Educators sign up blocked by AVE

When trying to sign up for Microsoft Learn for Educators the sign up fails with the verification throwing up an error that the domain was blocked by AVE.

The email from the domain used as institution email for verification is a M365 tenant with educative licenses. Our students can use their student mail to sign up for Azure for Students. 

I have tried the linked Microsoft Forms link - But I have not gotten a response so far.

This is outside of the purview of Microsoft Customer Support, but it is also not directly related to our Azure/M365 Subscription.

What are my best options to resolve this?
