TFS - Cannot configure reporting services: "The server that you specified was not found or cannot be reached"

I'm try开发者_StackOverflowing to configure Reporting Services for TFS2010. Upon clicking on edit in "Reporting", in the Team Foundation Server Administration Console, I'm able to configure everything without error.

Warehouse:

Server: INDEPENDIENTE01

Database: Tfs_Warehouse

(Clicking test connection shows up a green mark)

Analysis Services

Server: INDEPENDIENTE01

Database: Tfs_Analysis

(Clicking test connection shows up a green mark)

Reports

Server: INDEPENDIENTE01

(Clicking Populate URLs shows up the correct urls)

Default Path: /TfsReports

But when I click ok, I get this message:

The server that you specified was not found or cannot be reached. Specify another server

I have two servers, one with TFS and WSS and the other one with SQL Server 2008. I already changed Report Server Database configuration to Native mode. Tried using Network Service account and a different Account aswell. I can access both urls (INDEPENDIENTE01/Reports and INDEPENDIENTE01/ReportServer) And apparently I have all needed ports opened too (Otherwise I think it wouldn't even populate the urls)

My problem is similar to this one: http://social.msdn.microsoft.com/Forums/en/tfsreporting/thread/cfcb3031-c19a-474d-aab4-3b88ecd248e1

Except it didn't solve my problem.

(I hate those unspecific error messages, what's wrong with microsoft...)

It was a problem with ports, oh well.
