While figuring out the BizTalk 2016 Feature Pack 1 ALM feature, the setup & configuration of the Visual Studio Team Services (VSTS) build agent gave me some issues while configuring:
The error reads:
Exception of type ‘Microsoft.VisualStudio.Services.OAuth.VssOAuthTokenRequestException’ was thrown.
After searching for quite some time, I noticed the clock on my Virtual Machine was off. Strange, since Hyper-V will synchronized it quite fast after a resumed save.
Funny enough, after retrying, this seemed to do the trick. Long story short: if you have the above error, make sure the clock of your machine is synchronized.
Cheers,
