TF31002: Unable to Connect to this Team Foundation server

Question

I have a server that the team foundation server is installed on. I can connect to TFS from several computers, but I can't connect to its from my laptop through internet. I can connect to it from web, but I can't via team explorer.

Indeed I can't add server via team explorer in visual studio, and I receive following error.

I have connected to this server for 3 months. Then I deleted the team project from server and worked offline. Now I want to add my solution to TFS, but I can't connect to it.

Answer 1

Flushing TFS cache fixed this error for me. To do so;

Delete the contents from the following folders

• C:\Users\<>\AppData\Local\Microsoft\Team Foundation
• C:\Users\<>\AppData\Local\Microsoft\VisualStudio
• C:\Users\<>\AppData\Local\Microsoft\VSCommon

Go to the Visual Studio IDE folder in command prompt and run the following command "devenv /resetuserdata" from the Visual Studio IDE folder.

• Typical location for 64 bit: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE
• Typical location for 32 bit: C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE

Also, not sure if it made a difference but I also deleted this registry key;

• KEY_CURRENT_USER\Software\Microsoft\VSCommon\12.0\ClientServices\TokenStorage

If you are using an older version of VS than TFS, make sure you install the forward compatibility packs.
