Python - SSL: CERTIFICATE_VERIFY_FAILED

Question

I have a python script that uses the VirusTotal API. It has been working with no problems, but all of a sudden when I run the script I am getting the following error: urllib2.URLError: I believe it may be our web proxy that is causing the issue. Is there a way to prevent it from verifying the cert? Here is the portion of the code that uses the API: json_out = [] url = "https://www.virustotal.com/vtapi/v2/file/report" parameters = {"resource": my_list, "apikey": ""} data = urllib.urlencode(parameters) req = urllib2.Request(url, data) response = urllib2.urlopen(req) json_out.append (response.read()) JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

I believe it may be our web proxy that is causing the issue. Is there a way to prevent it from verifying the cert? If you assume that a SSL intercepting proxy is denying the connection then you have to fix the problem at the proxy, i.e. there is no way to instruct the proxy to not check the certificate from your application. If instead you assume that there is a SSL intercepting proxy and thus the certificate you receive is not signed by a CA you trust then you should get the CA of the proxy and trust it in your application (see cafile parameter in the documentation). Disabling validation is almost never the right way. Instead fix it so that validation works.
