Zyte Smart Proxy Manager(formerly Crawlera) performs HTTPS requests using CONNECT method, transparently tunnelling packets over default HTTPS port 443 to and from the destination server in a secure session.
To fetch HTTPS web pages through Smart Proxy Manager you need to download and install the certificate file for Smart Proxy Manager Certificate Authority or disable SSL certificate verification in your HTTP client.
The Smart Proxy Manager Certificate Authority can be downloaded here: zyte-proxy-ca.crt.
