**Description**  
As of 8/25/2020, Return URL, even if specified as http://, now attempts to return the user to https:// after authentication. All browsers.

This is a critical break in functionality.

This was not happening on 8/24/2020 or earlier.

Hey @edu_dev4,

Make sure to use a redirect url that is secured with `https`. That being said, I will see when this change was made.

Thanks,  
Tommy

Unfortunately at the moment we aren’t able to. Requires some major configuration changes across about a hundred sites. Browsers tend to complain about self-signed certs as well, so definitely not optimal.

Thanks for researching!
