我刚刚将我的 Nextcloud 实例更新到 19.0.5，然后更新到 20.0.2（内置更新程序）。
第一次更新后，Web 界面和客户端都遇到了连接问题（504 Gateway-Timeout），并且当连接最终接通时，响应速度很慢。我设法返回“设置”页面并从 19.05 更新到 20.02，但连接问题仍然存在。
处于维护模式时，页面正常加载。
输入我的 IP 地址即可非常快速地加载 nginx 页面。
输入我的 nextcloud 域名https://www.ssllabs.com/ssltest/显示我的安全评级为 A+。我确定要清除缓存，以便它必须建立新的连接。
我已经采取了一些步骤来诊断问题，但仍然一无所获：
重新启动 nginx
sudo systemctl reload nginx
sudo nginx -t
表明
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
我检查了：/var/log/php7.4.log 并发现了很多这样的行
05-Dec-2020 12:06:50] WARNING: [pool www] server reached pm.max_children setting (5), consider raising it
我去了：/etc/php/fpm/pool.d/www.conf 并将 max_children 增加到 40
并且 PHP 似乎运行良好：

我设置了 PHP 来显示信息
sudo nano /usr/share/nginx/html/info.php
<?php phpinfo(); ?>
但是，它并没有显示信息，而是在浏览器中导航到 localhost/info.php 要求我打开一个文件。
我正在使用 NetHogs 监控服务器，发现当我从远程 Web 浏览器联系服务器时，有大量 php-fpm：池 www 进程参与，但仅发送/接收~1KB/秒。

我现在不知道该怎么办。我的 nextcloud 实例现在几乎没用了，直到昨天我还在使用它。我希望有办法解决这个问题，而不必重建整个实例。
在此先感谢对此有任何想法的任何人。
答案1
我在 /etc/nginx/nginx.conf 中将 time_out 设置为 600 秒：
proxy_connect_timeout 600s;
proxy_send_timeout 600s;
proxy_read_timeout 600s;
fastcgi_send_timeout 600s;
fastcgi_read_timeout 600s;
sendfile on;
然后我可以导航到 Nextcloud 网络界面中的应用程序页面（等待约 5 分钟才能加载）并禁用上述错误消息中出现的 Collabra。
/var/log/nginx/error.log 中的示例：
2020/12/06 10:43:25 [error] 1064#1064: *13019 open() "/usr/share/ngin/html/thinkphp/html/public/index.php" failed (2: No such file or directory), client: 134.175.245.162, server: collabra.ddns.net, request:"GET /thinkphp/html/public/index.php HTTP/1.1", host: "24.202.235.154"
禁用 Collabra 应用程序后，Nextcloud 网络界面中的所有页面均按预期加载，并且 Nextcloud 桌面和 Android 客户端同步时没有延迟。
