AADSTS50011: The reply URL specified in the request doesn't match registered the reply URLs

Is this a common occurrence;  does anyone know how to get around this issue? 

"AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application: 'my application client id'. "

I've followed the directions explicitly in these two documents, and reviewed others to see if I was missing anything.  Reviewing responses to others' issues with the same problem did not resolve the failed auth issue. 
https://docs.microsoft.com/en-us/azure/app-service/configure-authentication-provider-aad
https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-configure-app-access-web-apis#add-redirect-uris-to-your-application

I have an Azure Web App that has been registered.  I can go to Azure Portal Home >> App registrations >> My App >> Endpoints, add all of the OAuth endpoints under the Redirect URIs and still cannot get fully logged in.  

I tried the <app-url>/.auth/login/aad/callback redirect format from one of the above articles with no success.  I've tried https://myapplicationname.azurewebsites.net/.auth/login/aad/callback, https://login.microsoftonline.com/mytenent/oauth2/v2.0/authorize (as well as the three other endpoints with this format), https://login.microsoftonline.com/common/oauth2/v2.0/authorize (same with other three endpoints), etc. 

When I run in debug on my localhost:44321/ the web app launches, prompts for authentication, and is successful each time, however, always fails with the same subject error any time I deploy the build to Azure.  My localhost addresses are listed in the Redirect URIs, so that makes sense the local deployment is successful but I cannot figure out why the deployed web app always fails when it goes live.  I've tried everything that I could possibly think of with different combinations, but no luck getting past the auth error so any insights would be greatly appreciated.
