Nginx 反代， ios 系统 safari 报错 503

[xmlf]

在 Nginx 中使用反代+frp，安卓和 windows 下 Chrome edge Firefox 都能正常访问。使用 ios 中 safari 访问提示 503 service temporarily unavailable

同样数据不使用反代，ios 中 safari 访问正常。

下面是反代配置，求大佬指点迷津～～

proxy_pass https://www.xxx.com:2443;

proxy_ssl_server_name on;

proxy_ssl_verify off;

    proxy_set_header X-Real-IP $remote_addr;

    proxy_set_header X-Forwarded-For $proxy_add_x_

forwarded_for;

    proxy_set_header Host $host;

 proxy_set_header X-NginX-Proxy true;

    proxy_http_version 1.1;

    proxy_hide_header X-Powered-By;

    proxy_set_header Upgrade $http_upgrade;

    proxy_set_header X-Forwarded-Proto $scheme;

    limit_except GET POST {

    deny all;

    }

你可以试试 frp 客户端 不要设置 ssl
而在 nginx 端 设置 ssl

github issue 中有 人给出这个问题的解决方法 但我试了 没成功。
好像 作者说过 不推荐用 nginx 反代。

@imWBB 我就是在 nginx 端设置 ssl 的，其他系统中浏览器都正常。就是 ios 中 safari 无法访问

排查后端 apache 日志发现，当 ios 设备打开网页会出现大量下列错误：
