Redirect error for asp.net hosted blazor app using Azure App Services

I have migrated an asp.net hosted blazor wasm application to Azure App Services. When authenticating from the Blazor app I am getting a url redirect error (Callback URL mismatch.
The provided redirect_uri is not in the list of allowed callback URLs.). I have entered the custom domain name in the appropriate sections on the Auth0 setup pages. I setup the application within the past 4 months and I assume that it is using the universal login form. Authentication has been working flawlessly while I have been testing from localhost and another local url. Is this an issue with Azure App Services or am I missing something else.

Thanks
