Did you wait for 24 hours after enabling the api?
Try testing the account to make sure that it works outside of code. Use the APIs explorer:
https://developers.google.com/adsense/management/v1.4/reference/accounts/list#try-it
Authenticate and try to fetch accounts list.
If that works, make sure you are connecting to the API using that account credentials.
Edit:
Perhaps one of these can help:
