I'm using VS 2017 preview 3, along with the xamarin updater. I was able to build fine a few hours ago. Now, even though the mac agent is connected successfully, i'm getting
The Xamarin Build Agent is not running on the Mac. An active Build Agent is required to perform the build
I've completely wiped xamarin from the mac and reinstalled vs-mac along with the alpha channel updates. i've also followed through all the steps in the 'connection troubleshooting' page. nothing jumps out at me from the logs, and a diagnostic build log doesn't show anything.
regular VS can build OK.
very frustrated. no clue what got changed. i had created a new xamarin app, and it built and ran in the live player just fine. then i went to xamarin university and was following along with the mytunes sample. downloaded it, tried to build, and couldn't.
