How can I extend my education plan?

I’ve received an email saying:
“If you're still a part of an educational institute, apply here to extend your Educational Plan...”

But that link seems to be broken, gives error "37f0689d-b1bb-4da9-9324-d242da911cee"

Since I cannot reach the site through that email:

What’s the process to extend the education plan?

Thanks a lot!
