Duo MultiFactor- Unauthorized

We have a login system that is working great with username and password login. When we enable the rule for DUO MFA it works when testing in the “rules” page of the Auth0 dashboard. However, when we test against our login the user is prompted for MFA from DUO, the DUO window shows login success, then we are redirected to a page from auth0 which shows "Unauthorized:. We are at a loss for why the MFA login is not working. any suggestions would be helpful.

Hi @eli.webster,

Welcome to the Auth0 Community Forum!

Are you just getting unauthorized? Any other specific message in the error?

Warm Regards,
Dan

Just the word “Unauthorized” in the corner of the web page and the website source shows error 401
