I have just deployed Jenkin and wanna integrate with TFS Plugin. Normally, i connect to TFS via Visual Studio with info
Name: servername
URL: http://servername:8080/tfs
But with Jenkin, i can not connect with error:
"*Started by user anonymous
Building in workspace /root/.jenkins/jobs/Test project/workspace
FATAL: com.microsoft.tfs.core.exceptions.TECoreException: The SOAP endpoint http:/servername:8080/tfs/Cardlab/Services/v1.0/Registration.asmx could not be contacted. HTTP status: 503
java.lang.RuntimeException: com.microsoft.tfs.core.exceptions.TECoreException: The SOAP endpoint http://servername:8080/tfs/Cardlab/Services/v1.0/Registration.asmx could not be contacted. HTTP status: 503....*."

I configure with detail below:
Server URL: http://servername:8080/tfs/Cardlab
Project path: $/Payjr
I also tried with the IPAddress instead of servername but still not works. NSlookup working for both.
Anyone can help please. Very appreciate your support. Cheers
