Snapshot fails first time

[rebel2234]

Using the get-snapshot.py example I have to run it twice to actually get a snapshot. First time always fails then second and subsequent times will save the snapshot where I have specified. If I wait a minute or so and then try to run it again, the same process is repeated. How do I get it to grab a snapshot without having to run the code twice?

During handling of the above exception, another exception occurred:

Thinking this is because the http module tries Basic auth, then switches to Digest. Could probably set a preferred auth method in the class. That's what I see in wireshark and confirmed here:

python-amcrest/src/amcrest/http.py

Line 147 in 3c3fa58

self._token = requests.auth.HTTPBasicAuth(self._user, self._password)
