TF215097: An error occurred while initializing a build for build definition : Could not establish trust relationship for the SSL/TLS secure channel

Question

Hello,
We are facing an issue when triggering a new build using TFS 2013 Update 4, VS2013 Update 4 using TFVCTemplate.12.XAML template. All our other older build definitions just work fine but not the TFVCTemplate.12.XAML.  It seems to me that some certificate
might be invalidated. Can anyone please point me in the right direction? 
Thanks, 
Mitul

Hi Mitul,
Thanks for your reply.
It’s strange, if your old build definitions can work using the same TFS Build Server, that indicate your TFS Server configuration is correct and can works. But only new build definition with default TfvcTemplate.12.xaml template cannot build successful.
Please share your TFS Server detailed environment information here. And share your
Build Service Properties dialog screenshot here.
Try to clean the Cache for TFS 2013 manually(delete the content of the folder only, not the cache folder itself):
Clean the Cache folder on Server machine. The folder path is:
C:\Program Files\Microsoft Team Foundation Server 12.0\Application Tier\Web Services\_tfs_data.  
After cleaned, on Server machine, click Start and select
Run… to open the dialog box, then input iisreset.exe and click OK, wait it run completely.
Additionally, you can run the TFS 2013 Power Tools BPA to scan the installation of your TFS Server.
