Dynamics 365 with ADFS-federation with external client - Dynamics won't load

Posted on by 471
Hello,
 
I have an environment with Dynamics 365 v.9.1 On-Premises which has been configured with ADFS (Claims-based and Internet-Facing Deployment). We have also federated the ADFS-server with external clients ADFS-server so that they can login with their own usernames. Everything works perfectly fine If we try to login from the ADFS or Web Application Proxy server on the network where Dynamics 365 is, but from the external client (testing from their ADFS-server right now) we are having issues where the Dynamics is not loading. We are getting through the login screen and both ADFS-servers seems to accept the authentication. I can see in the address bar that the authentication is passed from one ADFS-server to the other and then it tries to load the Dynamics URL. I can even see that the URL changes from https://dynamics.url.com/Default.aspx to https://dynamics.url.com/main.aspx?forceUCI=1&pagetype=apps and there it hangs (see screenshot below).
 
Any suggestions?

    An update: the problem seems to be HTTP\2 feature on server 2019. I disabled this and everything worked as it should.

    Problem is fixed by setting up a new WAP-server thanks to this forum post: Problem with Dynamics 9.0 IFD behind a WAP

    Not sure what's happening here, but the important thing is that it is now working again.

    Here is another error message I am getting. Again, this works perfectly from inside behind the Wep Application Proxy and ADFS-server. The problem exist from external client only.
