I have a problem in my environment, I have arcserver version 10.2.1 and Portal for arcgis verson 10.2.1, I have configured all of them to work together without any problem, my only problem was to add arc server to portal as a hosting server and i fixed it by enabling connection through ports required.
My problem now is I try to open any added maps from the arc server to find it is not working so i tried to go to the arc server manager, it refuses my user and password stating that it is incorrect, but when I try entering http://my server/arcgis/admin, and enter the same user and password, it works fine, If i try to enter http://my server/arcgis/rest, I cannot see any of my services.
I tried connection from arcgis desktop, which was working before, it refuses to connect and gives me 'Bad syntax error' I removed the certificate, and try access using http only but no change I tried using the https url no change I defined the webadaptor again no change..
Once you federate a server to portal, you have to direct connect to your ArcGIS Server instance via port 6443 to be able to connect to ArcGIS Server. You must bypass the Web Adapter completely
