I have been successfully able to use Release Definition API on our TFS 2015 Update 3 on prem instance using API Version "3.0-preview.1". But ever since I started testing this on VSTS, I am continuously getting a 404 error stating
Page not found
And a long block of HTML.
I am using PowerShell to call the API. And I am creating the API request as mentioned in the documentation using Personal Access Token and Alternate credential method.

Can someone let me know if I am missing something.
