josevandeb

    listen       8011;
    server_name 127.0.0.1;
    location / {
    proxy_pass https://imagedelivery.net;
    proxy_set_header X-Forwarded-Host $host;
             proxy_set_header X-Forwarded-Server $host;
             proxy_set_header  Host  $host;
            proxy_set_header  X-real-ip $remote_addr;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}



error.log 是下面的。

感觉是没设置 ssl name

灌水王

加一个

1. proxy_ssl_server_name on;proxy_ssl_name $host;

复制代码

灌水王

目测是cloudflare的ssl选项得切换到flexible

yuanyuanlop

跟上游的服务器通讯失败，估计不是这两段配置文件的问题吧。

3楼提到的 proxy_ssl_server_name on 可能在有些情况下有用，遇到过一回，楼主不妨试下。

灌水王

设置了，错误一样

titati

知道了，不能设置$host 要手动设置cf的那个域名。

灌水王

1. proxy_set_header  Host  $host;

复制代码

你这么写的话，就会用 127.0.0.1 去请求 Host

所以你得改成

1. proxy_set_header  Host  imagedelivery.net;

复制代码
