E-mail not accepted i form field (embedded form mailchimp)


I have testet a sign up form on my website several times with my private email address (gmail).
Suddenly my email is no longer valid (error - something went wrong message).

It its not a problem with other emails addresses only my private email address I’ve used for testing.

Can anybody help me have an answer for this Issue?

Kind regards Anders
