Error scraping with selenium (Firefox) in python

I'm scraping with selenium (Firefox) in python.
I'm having trouble accessing the https page because I got an error.

You can access the http page.

If anyone knows the solution, please let me know.

Using Firefox is a prerequisite.

Environment

centos6(vagrant)

python 3.5

selenium (3.0.2)

Xvfb

Firefox 45
