RE: Javascript rendering error (pyppeteer.errors.PageError: net::ERR_CERT_SYMANTEC_LEGACY) #174

Same traceback message as #174

Traceback (most recent call last):

As suggested in oldani's comment, I do have verify=False in my request.

import requests_html
s = requests_html.HTMLSession()
r = s.post(url, data, verify=False)
r.html.render()

It appears at least at least one other user was facing the issue after it being closed.

Google Chrome no longer considers SSL certificates issued by Symantec before 1st June 2016 as valid, and pyppeteer uses Chromium under the hood. Perhaps it's worth using Let's Encrypt instead, if that's possible?

Also, an FYI: using verify=false will help you circumvent SSL certificate errors, but it can expose your application to security risks such as man-in-the-middle attacks. Consequently, it is probably worth using with caution...
