New User account: too_many_attempts but No Auth0 User

New user account tries to login.
“too_many_attempts” error

User email is blocked by auth0
BUT: there is no Auth0 “User” to unblock.
Tried to delete the user’s original site account and recreate.
Must use the same email address for membership company domain issues.
User CANNOT login with too_many_attemps error!!!
I cannot unblock user at Auth0 as the User does not exist there (emailaddress)
Any help will be appreciated.

Can you check if there are any User Blocks for the email address associated with that new user:

If so, you can delete the User Block based on that email identifier:
