Hi @acecauis
Thank you for posting regarding the issue that you are facing with your callback URLs.
I am sorry about the late reply to your inquiry.
As far as I have checked on your tenant, the Allowed Callback URLs and Allow Login URLs still seem to be under http:// instead of https://.
You can also check that your login request does not parse a different URL for the redirect_uri than the one expected in the Callback URL. I recommend checking your /authorize request, specifically the redirect_uri query parameter, to make sure the URL points to the URL specified in your Allowed Callback URLs of your Application’s settings
As an alternative, you can attempt to force the HTTPS as follows:
HttpContext.Request.IsHttps = true;
await HttpContext.ChallengeAsync(Auth0Constants.AuthenticationScheme, authenticationProperties);
Otherwise, if you are still facing issues with your page being redirected to the wrong URL while using custom domains, please review this Knowledge Article regarding possible issues with certificates.
If you are still having an issue or any other questions, feel free to reply back to this post.
Kind Regards,
Nik
