无法使用 nagios 和 nginx 访问 localhost

我已经按照这个链接安装了 nagios，我已经启动并运行了 nginx。问题是我不断获取用户名和密码来进行身份验证。

当我删除 时auth_basic_user_file /etc/nagios/htpasswd.users;，我不会再收到该警报。但是这http://localhost/nagios给了我空白页。然后，当我使用 get that line back 时，我无法访问它。我什至尝试在这个线程中chown nagios /etc/nagios/htpasswd.users作为解决方案。

这是我的文件

htpasswd.users

yamen:NFy9PslWPh4Vo

我的网站

            location ~ "^/pagespeed_static/" { }
            location ~ "^/ngx_pagespeed_beacon$" { }
    }

nagios.conf不提供任何东西。

我把上面的用户名，一遍遍的通过，什么都没发生

感谢@PaulHaldane，我确实发现了错误，但仍然不知道为什么会发生。这是 nginx 错误日志。
