Tutor OpenEdx production server facing email password authentication issue

In the production server, we are encountering authentication issues for email-password login, despite having the same code base that works fine on the local server. This problem is specific to the Tutor Palm OpenEdx version in the production environment.

email password is correct but still facing issue in production not in local server

What’s the exact error you are getting, and where? The current context is not enough to understand what might be going wrong.

Getting “Email or password is incorrect.”
