Yesterday I created a new project in Codeplex. I created a connection from Visual Studio to the TFS server to which I was assigned, and successfully downloaded my solution. Today I am trying to connect to the Codeplex TFS server to work on a solution. When I try to open it, I get an error message:
Team Foundation Server https://tfs06.codeplex.com/ does not exist or is not available at the same time.
The remote server returned an error: (407) Proxy authentication required.
The enterprise environment I use uses proxy authentication, but yesterday it was not a problem. Any ideas on why it worked then and how to make it work now?
