Wordpress 在 Nginx Loadbalancer 上运行出现错误“页面未正确重定向”

Question

所以我为我的 wordpress 进行了这样的设置。

所有服务器均在 Centos 7 MariaDB 10.4.17 Php-FPM 7.4 PHP 7.4 NginX 上运行

服务器 1，前端负载平衡服务器服务器 2-3-4，使用 NginX 服务的 wordpress 应用程序服务器 4 MariaDB

Nginx 负载平衡设置在 2-3-4 服务器上的每个服务器上都使用标准 info.php 运行良好。它们使用循环法进行切换。

wordpress 本身在服务器 2-3-4 上运行良好。我必须在 wp-options DB 中更改 wordpress 的站点 URL 和主页 URL，以反映服务器的 IP 地址。例如，如果我正在测试 wp 服务器 2，则站点 URL 和主页 URL 指向服务器 2。

当我将 LB 下的所有服务器 2-3-4 与 wordpress 合并时，我收到此错误“页面未正确重定向”。我不太确定是否需要进行某些设置才能使 WP 在 Nginx 负载平衡器下工作。有什么建议可以解决这个问题吗？请帮忙？
