nginx多域配置失败

Question

502错误的网关错误，嗯我的dns没问题。我有一个名为＆＃39; app＆＃39;的文件夹。和＆＃39;网站＆＃39;在我的/ home目录中。

server {
    listen 80;

    server_name dashboard.abc.com;

    location / {
        root app;
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

server {
    listen 80;

    server_name abc.com

    location / {
        root site;
        index index.html index.htm;
    }
}

这里的一切都有意义，不确定哪个部分导致问题
