User cannot login via Zoom Popup Authentication

After our OAuth Zoom App got approval, the user cannot login to their zoom account via our site popup, which only redirect to a Zoom Sign In Page.

By doing the login via the Authentication Popup, the user always got wrong username and password, if they tried again many times a 500 response was responded. However, they could still login successful via Official Zoom Website, then authorized our Zoom App from the Authentication Popup.

The issue only happen when the user login as a zoom account, if they use a third party login (Google), it is still working fine.

Which App Type ?

Which Endpoint/s?
