RDWeb External Access Failing

I just installed a Server 2012 R2 RDS deployment.  I have published Apps and they are all working internally.  Externally they are failing.  I have installed ad configured the RD Gateway, as well as a 3rd party SSL certificate.

I am assuming I have a firewall issue.  I have opened port 443 ONLY so far.  Do I need more ports open to allow remote Apps externally?

Not with RDGateway. 443 is all you need from external to the RDGateway server.

URL or SSL issues most likely. With no errors, it is tough to be more specific.

My internal FQDN is server1.ABC.local and my external name is apps.ABC.com.  My SSL cert matches the external name.  Is that a supported configuration?

Problems using Powershell and Active Directory?

As long as you configured RDGateway that way via server manager.

Can you provide a link so I can verify that? Not sure where to check.

Ok... I have managed to change the URL to the external FQDN with a powershell script I found online.

Now I believe I have a permissions issue....  When I access the Remote App site internally it works, but once logged into the web page... and I launch an app it prompts me for credentials again.. but then the app launches....

When I go to do the same thing externally, the same thing happens but when I put the credentials in to launch the app it fails and gives the attached error message....

What could this be?
