Sometimes company blocks some websites in their network so employees can't access these websites. Whenever they try to visit these websites, it shows "Access Denied because of company's policy". It causes connection error in reachingmain python website.

The --trusted-host option mark the host as trusted, even though it does not have valid or any HTTPS
