We're running TFS 2015 update 2. When a build starts, it says "Waiting for an agent" then, 2 seconds after, the build fails. I looked whether the agent pools were running, and all of them were on green (as I understand this is expected). Also, I looked whether the TFSJobsAgent was running, and it's ok. If I download the zip log from de build process, it is empty, so i don't know what i'm doing wrong. i tried to create a new agent pool, and run the build process on that agent, but i got the same result.
Any ideas on how to tackle/solve this?
PS: All the builds were working fine a week ago.
