I'm guessing that you have a much older version of Python 2.7, and it does not have the appropriate SSL libraries.

Have you considered installing one of the RPM or DEB packages (if this is a linux box)? These pre-packaged versions come with their own version of Python 3.6, and are fully up-to-date.

If it's some other unix-like system (FreeBSD, etc) that cannot use DEB/RPM packages, have please consider installing Python 3.5 or better still, 3.6. Older versions of Python 2.7 may simply not have the correct SSL libraries/modules installed. Curator is tested with the latest versions of Python 2.7, 3.5, and 3.6. Older than 2.7.10 or 2.7.11 may be in need of an update.

After I upgraded my python to 3.6, the problem was solved. Thank you very much for you help!
