Can't select machine group from Build tasks dropdown in TFS 2015.2

问题

I'm trying to use the Visual Studio Test Agent Deployment Build vNext task in TFS 2015.2. I added a machine group in the Test tab, but when trying to select the machine group in the dropdown in the build task for the Test Agent Deployment, the UI thought that there were no groups! (clicked on the dropdown, wouldn't have anything show up)

We refreshed the page and no difference. And this issue seems to appear for all of the build tasks. We tried a Windows File Copy task and typed in the Machine Groups manually and the task succeeded, so TFS does recognize the groups. I'm experiencing the issue as a TFS Admin. This has happened to more than one environment of an install for us.

Has anyone else seen this issue with TFS 2015.2?

Not see this issue on my side. Try another supported browser to see whether you would have the same issue.

Supported browsers:

Internet Explorer, versions 9, 10, 11, and 12
Mozilla Firefox, latest version (27)
Google Chrome, latest version (32)
Safari (supported on Macs only), version 7

Same problem here, I posted a request on the microsoft forums.

The cause is a call to the distributed task coordinator:
