Configure ArcGIS Server to use ArcGIS Portal from Services Directory

Question

My organization have deployed a Federated ArcGIS Portal which uses Windows authentication. I manage several federated ArcGIS Servers in the same domain and are accessible in the same way. My network does not allow using the defaulted http://www.arcgis.com portal for previewing services since we secured the servers per guidance. I made the necessary changes to point the Services Directory's ArcGIS.com URL setting to my organization's portal as below:

Unfortunately, when I click on "View In: [Organization] Portal", I get the screen below:

The first thing that strikes me is that it calls it as HTTP, not HTTPS, which is weird since that's not how it was configured. It might explain the access denied, because it's not allowed on network, but that's not reflected on the browser's address bar.

* Is there something that needs to be done for the portal to allow its usage on my ArcGIS Server? I assumed that wouldn't be the case if it works in same way as the default arcgis.com site.
* Why does the error shows up as an unsecured/http address?
* What does the error message means by "on this server"?

Thanks in advanced.

No, I think that error is thrown by something in front of your Portal, like a reverse proxy or less likely, IIS. The error page isn't a normal one you would see either in Server, Portal, or IIS.  I would talk to whoever has knowledge on the configuration of the environment to track down the problem.  If you know the mahcine name running Portal, you can also bypass the front-end of it and reach Portal directly:

https://portal.machine.com:7443/arcgis/home/webmap/viewer.html?url=<serviceurl>&sourceid=sd

If it works directly through 7443, then that would confirm it's a problem with whatever is in front of the Portal.

Jonathan, Your statement "The error doesn't appear to be a Portal error" got me thinking. could there be a setting in my ArcGIS Server (10.3.1) that is by-passing what's given in the Services Directory value?

Yes, I am able to browse to, authenticate and view/create content. The portal was deployed by another team within my organization, so I don't how it was exactly configured. I heard they had ESRI come up and set it up for them. I haven't addressed the issue to them, yet (assumed was doing something wrong). Yes, WA=windows authentication. Nothing different seems to happen when I browse to "https:///geoportal/home/webmap/viewer.html?", stays right on the page. I get the same error when manually complete the parameters "?url="&sourceid=sd on the address bar.
