You are attempting to authenticate to Google Analytics using a Service account. Service accounts by default do not have any google analytics accounts.

Add service account to Google Analytics account The newly created service account will have an email address, -@developer.gserviceaccount.com; Use this email address to add a user to the Google analytics account you want to access via the API. For this tutorial only Read & Analyze permissions are needed.
