我在 Cloudflare 的 Pages 上部署了 github 的项目，默认域名是.dev 的，于是我绑定了一个在 cloudflare 上托管的域名，假设是 abc.com ，项目解析的是 pj.abc.com ，我访问 pj.abc.com 的时候是 reset ，因为长城的原因，我只能使用 VPN ，但这不是一个好办法，于是我找到了一台能够翻墙的 Linux 服务器，使用 nginx 对这个域名进行反向代理，但是似乎访问时会报 502 ，这个是啥问题引起的？

server {
    listen 6659;
    server_name pj.123.com;
    access_log /var/nginx/logs/http_proxy_access.log main;
    error_log /var/nginx/logs/http_proxy_error.log debug;
    if ($host ~* "^pj.123.com$") {
        rewrite ^/(.*)$ https://pj.123.com:7956$request_uri permanent;
    }
}

server {
    listen 7956 ssl;
    server_name pj.123.com;
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

}

我看了下日志，似乎是报 SSL 的问题

试了你俩的，好像还是 502 ，反向代理 dev 那个也一样

哦，好像是缓存，为啥反向代理 dev 就可以，反代自己的域名就不行啊？
