无法从外部看到节点 STRAPI CMS 应用程序 - ERR_CONNECTION_REFUSED

Question

我尝试在我的 VPS 上运行 STRAPI CMS。

应用程序通过 PM2 运行，内部 curl 正常，我看到应用程序的响应

curl -v http://127.0.0.1:1337

但外部 curl 是个问题，现在我只想通过http://89.221.222.178:8090（仅用于切换到“域模式”之前的测试）。

curl -v http://89.221.222.178:8090
* Rebuilt URL to: http://89.221.222.178:8090/re (v6)
*   Trying 89.221.222.178...LLOW       Anywhere (v6)
* TCP_NODELAY set          ALLOW       Anywhere (v6)

* Failed to connect to 89.221.222.178 port 8090: Connection refused

curl: (7) Failed to connect to 89.221.222.178 port 8090: Connection   refusedata.poutnicesty.cz

防火墙允许端口

...
sudo ufw status
8090                       ALLOW       Anywhere
8090/tcp                   ALLOW       Anywhere
8090/tcp (v6)              ALLOW       Anywhere (v6)
...

Nginx 配置：

server {
        listen 8090;
        listen [::]:8090;

       root /var/www/data.poutnicesty.cz/;

        index index.html index.htm index.nginx-debian.html;

        server_name 89.221.222.178:8090;

        gzip            on;
        gzip_types      text/plain application/xml text/css application/javascript;
        gzip_min_length 1000;

        access_log  /var/log/nginx/data.poutnicesty.cz.access.log;
        error_log  /var/log/nginx/data.poutnicesty.cz.error.log;

        port_in_redirect off;
        proxy_set_header Host $host:$server_port;

location / {
        proxy_pass http://127.0.0.1:1337;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_pass_request_headers on;
    }
}

我认为仅允许端口就足够了（对于其他“子域”，它可以工作，例如：端口：8050 - 但我在那里使用 nuxt 应用程序进行了测试，而不是 strapi）。

任何想法？

多谢。
