Cannot connect to TFS site from Eclipse

Question

I have a problem with connecting to a visualstudio.com TFS site from Eclipse.

With proxy set in network settings to "Native"
I can connect fine from IE and the Eclipse internal browser. I log in, and all is fine.
When I then go to team explorer and try to add server I get "Error connecting to server: credentials must not be null"

I change the proxy settings to "Direct"
Again can connect without any issues from the browser
When I try to add server from Team Explorer, it attempts to connect but times out after a couple of minutes.

I have cleared IE cache/cookies, and it made no difference

I have also installed a fresh instance of Eclipse (v4.2.1) with TFS plug-in for Eclipse (version 11.0.0.201212121120) on a different server but this just brought the same issue.

I have exhausted forums trying to find a solution to this issue but cannot find anything.

Any advice or assistance would be much appreciated

Answer 1

Sorry about the issue, can you connect from CLC or any other client such as VS?

Answer 2

Unfortunately not. I get the same behaviour.

Answer 3

Anyone else have any input? It is becoming quite critical :(

Thanks

Answer 4

Hi, apologies for the delay, this was a difficult bug to track down as it requires a certain set of circumstances to appear.

It appears that this is a bug when creating an HTTP channel to a TFS server that requires OAuth authentication (such as Team Foundation Service) when using a proxy that requires basic authentication.

We will have a fix for this in a future update.
