http - NGINX 反向代理 - ERR_TOO_MANY_REDIRECTS - 如何修复？
问题描述
到目前为止，我在主服务器 B 93.151.75.75 上使用了一个 PHP 脚本，它位于 NGINX 反向代理服务器 A 173.176.183.183 后面。关于 website2.com 域名。它奏效了。现在我在 website2.com 域名上安装了一个新的 PHP 脚本并且崩溃了（（（如果我在脚本设置中设置了 HTTP 协议，我得到混合内容错误。如果我打开 HTTPS 协议，那么我得到一个错误 - ERR_TOO_MANY_REDIRECTS。我尝试将此脚本放在 website3.com 域名上并且效果很好。当然，我的主服务器 B 93.151.75.75 在 website3.com 域名上具有来自 Cloudflare 的 SSL 证书。我该如何制作这个 PHP 脚本在 website2.com 域上正常工作？我在服务器 A 173.176.183.183 反向代理设置中做错了什么？
我附在 NGINX 反向代理 A 173.176.183.183 配置和来自 Redirect Checker 的信息下方。我将非常感谢您的建议！

解决方案
我需要将此行添加到常见的 Nginx 反向代理选项中-
proxy_set_header X-Forwarded-Proto $scheme;
问题就解决了。
