SubjectAltNameWarning and IntegrityError

[Gwonke]

On execution of s.sync() I receive a warning and an IntegrityError.
This error occurs with my code (which previously worked) and with the tmpo.ipynb example code.
I run Jupyter Notebook from Anaconda with Python 2.7

Warning:
...\AppData\Local\Continuum\Anaconda2\lib\site-packages\requests\packages\urllib3\connection.py:337: SubjectAltNameWarning: Certificate for api.flukso.net has no subjectAltName, falling back to check for a commonName for now. This feature is being removed by major browsers and deprecated by RFC 2818. (See urllib3/urllib3#497 for details.)
