phpMyAdmin错误504重新加载网关超时

我的phpmyadmin有一个非常恼人的问题。它突然出现了。据我所知，我的专用服务器没有发生任何更改

当我试图在我的浏览器中执行任何查询或显示需要1秒以上时间才能执行的视图（windows 7上的firefox，ie的行为相同）时，我会出现以下错误：

Error in Processing Request 
Error code: 504 
Error text: Gateway Timeout

查询可以有也不需要有count（*）。他们在5米到50米的桌子上工作

有时，当我单击phpmyadmin中的任何链接时，如“浏览”、“服务器”或“结构”，也会出现相同的错误

php脚本可以在同一个专用服务器上运行更密集的查询，并且工作完美

以下是一些技术细节：

Database server
•Server: Localhost via UNIX socket
•Server type: MySQL
•Server version: 5.5.38-0ubuntu0.14.04.1-log - (Ubuntu)
•Protocol version: 10
•User: XXX@localhost
• Server charset:  UTF-8 Unicode (utf8)  

Web server
•Apache/2.4.7 (Ubuntu)
•Database client version: libmysql - 5.5.38
•PHP extension: mysqli Documentation

phpMyAdmin
•Version information: 4.2.3deb1.trusty~ppa.1

我在网上找到了一些线索，并尝试在conf.inc.php文件（见下文）中添加最后两行，但在重新启动服务器后也没有任何更改：

<?php

 *
 * This file overrides the settings made by phpMyAdmin interactive setup
 * utility.

 * For example configuration see

也许您可以检查或增加/etc/nginx/ngix.conf中的nginx超时设置？检查代理发送超时和代理读取超时。
最后，我发现这不是我服务器上的问题，但我当时的internet连接提供商只是取消（发送此错误消息）所有需要10秒以上才能完成的https请求
 只需删除浏览器上“yourwebsite.com/phpmyadmin”的cookies即可。
如果您将php fcgi与Nginx一起使用，请将其添加到

                fastcgi_intercept_errors on;
                fastcgi_buffers 8 16k;
                fastcgi_buffer_size 32k;
                fastcgi_connect_timeout 900;//in 900 timeout
                fastcgi_send_timeout 900; //in 900secend
