NGINX + VPS-奇怪的404错误，直到重新启动

Question

我正在尝试为我的VPS Web服务器设置nginx，并在单独的文件夹中安装2种不同的wordpress。我没有使用nginx的经验，因为我一直使用apache和htaccess，所以可以得到任何帮助：）

我遇到一个奇怪的问题：浏览一个文件夹（/ markuz）时出现404错误，但它似乎不是由nginx生成的（如果我尝试其他未配置的文件夹，则使用nginx会得到404错误写在页脚上，但不在此特定文件夹上...）

我还遇到了第二个问题，例如漂亮的永久链接，例如/ wordpressfolder / product / name被重写为/ wordpressfolder / name等。

这是我的Nginx配置

    listen 80;
    listen [::]:80;
    server_name _;
    return 301 https://$host$request_uri;

    listen 443 ssl http2;

    location ~* .(js|jpg|jpeg|gif|png|css|tgz|gz|rar|bz2|doc|pdf|ppt|tar|wav|bmp|rtf|swf|ico|flv|txt|woff|woff2|svg)$ {

    add_header Pragma "public";
    add_header Cache-Control "public";
    }
}

我在每个位置块中尝试了很多带有根/别名的组合，但始终存在404错误。 有趣的是，如果我重新启动vps计算机并首先打开/ markuz，则/ lepassionidimari会显示404错误，直到下次重新启动为止，反之亦然。

那会是什么？ 谢谢：）
