Azure Web App + Active Directory with domain mapping issue

I have published an application as an Azure WebApp which uses Azure ActiveDirectory for my authentication.

This requires a redirect to AD and re routes back to my web app after authenticated.

This works flawlessly using the xxxx.azurewebsites.net uri, but is not working properly with domain masking.

How can I use my custom domain with ActiveDir auth?

The masking works without the azure auth, but the reply URL throws an error (which I will post soon).

Have you added the custom domain as a reply URL to the app in AAD? – juunas Jul 31 '19 at 11:48
@juunas yes I have – Tom Crosman Jul 31 '19 at 15:32
@TomCrosman Have you secured your custom domain with ssl binding? The reply url configured in azure ad must start with `https`. So your custom domain url must be totally the same as the reply url. – Tony Ju Aug 01 '19 at 06:38
Yes, I paid for and implemented SSL. Thank you for the guess though. – Tom Crosman Aug 01 '19 at 06:39
@TomCrosman The issue still exists even if you used https? – Tony Ju Aug 01 '19 at 06:40
@Caiui Ju yes, even when Https – Tom Crosman Aug 01 '19 at 06:41
@TomCrosman This does't make sense. What is the error message? – Tony Ju Aug 01 '19 at 06:42
The error says the reply URLs don’t match. But I configured them correctly... – Tom Crosman Aug 01 '19 at 06:45
@TomCrosman You can catch the redirect_uri in the browser. – Tony Ju Aug 01 '19 at 06:50
@TomCrosman The reply url should be something like `https://xxx.xxx.com/.auth/login/aad/callback` – Tony Ju Aug 01 '19 at 06:54
@TomCrosman https://i.stack.imgur.com/SJjUZ.jpg Check it with the reply url you configured on Azure portal. – Tony Ju Aug 01 '19 at 06:59
Yeah my redirect shows as expected in the url – Tom Crosman Aug 01 '19 at 07:02
@TomCrosman Can you provide the reply url configured on Azure portal? – Tony Ju Aug 01 '19 at 07:08
