如何用 Nginx 方向代理 HTTPS 到 HTTP？

想通过自己的主机代理一个第三方 HTTP 服务

部分 nginx 配置如下，现在访问 https://mydomain.com 提示 This site can ’ t provide a secure connection 和 ERR_SSL_PROTOCOL_ERROR

求解

server {
    listen 443;
    server_name mydomain.com;

    ssl on;
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/privkey.pem;

    ssl_prefer_server_ciphers on;
    ssl_session_timeout 1d;
    ssl_session_cache shared:SSL:50m;
    ssl_session_tickets off;

    location / {
        proxy_pass          http://anotherdomain.com;
        proxy_set_header    Host             $host;
        proxy_set_header    X-Real-IP        $remote_addr;
        proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header    X-Client-Verify  SUCCESS;
        proxy_set_header    X-Client-DN      $ssl_client_s_dn;
        proxy_set_header    X-SSL-Subject    $ssl_client_s_dn;
        proxy_set_header    X-SSL-Issuer     $ssl_client_i_dn;
        proxy_read_timeout 1800;
        proxy_connect_timeout 1800;
    }
}
