We are implementing URL hardening in Azure PaaS. We have added Azure front door urls to CM app. We have updated
Sitecore.Owin.Authentication.IdentityServer.config
on CM server with new url for identity server and
Sitecore.IdentityServer.Host.xml
on identity server with the new urls for Sitecore CM. But still the identity server redirects back to the old CM server url only and not to the Azure front door url for CM. Any inputs on what are we missing here?
