Http NGINX反向代理-错误太多\u重定向-如何修复？

到目前为止，我在主服务器b93.151.75.75上使用了一个PHP脚本，它位于NGINX反向代理服务器a173.176.183.183的后面。在website2.com域名上。它成功了。 现在我已经在website2.com域名上安装了一个新的PHP脚本，我崩溃了((( 如果在脚本设置中设置HTTP协议，则会出现混合内容错误。如果打开HTTPS协议，则会出现错误-ERR_TOO_MANY_重定向。 我尝试将此脚本放在website3.com域名上，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Cloudflare的SSL证书。 如何使此PHP脚本在website2.com域上正确工作？ 我在服务器A 173.176.183.183反向代理设置中做错了什么

我在NGINX反向代理下面附上173.176.183.183配置和重定向检查器的信息。 我将非常感谢您的建议

nginx.conf（nginx反向代理 173.176.183.183）

我需要将这一行添加到常见的Nginx反向代理选项中-

proxy_set_header X-Forwarded-Proto $scheme;

---

问题已经解决。

https服务器配置代理中的默认位置传递到http服务器。这可能导致重定向循环吗？@Cole Tierney，你能告诉我更多吗？如果

代理传递http://93.151.75.75

导致http主机重定向到https，然后可能导致重定向循环。

proxy_set_header X-Forwarded-Proto $scheme;
