Print when request is Unauthorized

[Erni]

When the request is Unauthorized, you get a message like:
SyntaxError: Unexpected token U
This is because it tries to parse the data object which is not a valid JSON object but a response like:
401 Unauthorized /_status
You could print this unauthoriezed message so the user knows the reason why it fails.

There should be better output now. Take a look if that helps.
