Custom domain still not working

I have a regular web application built with Flask, and I am using the universal login page (I have done some styling updates to the default page). I have successfully set up custom domain and pass the test in Branding->Custom Domains page.

When I try to log in though, this update does not appear on the address bar and I still see auth0 url. This page does not say how to do this for a python code with universal login page. Could someone give me examples/pointers?

Hi @amohajerani.

Welcome to the Auth0 Community!

When using the Python Flask SDK with custom domains, you must make sure to change the AUTH0_DOMAIN definition in your /.env file.

After that is done, it should open the login page with your custom domain in the URL structure:


As an additional test, you could paste the /authorize URL with your custom domain into a browser and see that it works.

I hope this helps!

Please let me know if you have any questions.
