Cannot register Application ID URI at Teams app SSO

Hi all,

I am tring to developing a Teams tab app which supports SSO. I deployed the app to the Azure App Service, and registered Azure AD app.

Single sign-on (SSO) support for tabs

However, an error occurred and the Application ID URL cannot be set. The error is:

Failed to update application property. Error detail: The host name should not be based on already owned domain paramName.

the Application ID URL is like below:

api://contoso.azurewebsites.net/00000000-0000-0000-0000-000000000000

When I contacted Azure support, I was told that azurewebsites.net is reserved by Microsoft. I was recommended to use https://contoso.azurewebsites.net/00000000-0000-0000-0000-000000000000, but it does not work.

App resource defined in manifest and iframe origin do not match

Is it any solutions?

Yes, I used fully qualified domain name. But it is the default domain for Azure App Service (*.azurewebsites.net).
