I followed the instruction on <https://www.youtube.com/watch?v=QjjcqT5hZzI> and was able to install TFS in my Windows Server 2012 successfully. I was able to access the TFS web site(<http://SERVERNAME:8080/tfs/>) from the browser so I thought it was all good.

When I tried connecting to it via Visual Studio 2015 Team Explorer, I got a 404 Not Found error. So I went back to my Windows Server 2012 and tested my Server URL in Team Foundation Server Administration Console. It gave me the same error. I can see it being hosted in the IIS properly and have been using Administrator account everywhere. The firewall is open for the port and I don't see how I can access the site but not the service on the same url.

Does anybody have any idea what I'm doing wrong?

Here is the error I get while testing Server URL. Note that it is the same I get during attempts to connect via Team Explorer.
