Nginx invalid parameter in upstream?

Question

Nginx

I want to set up nginx for my vps. You need to do a redirect so that you do not need to enter the port in the url. When setting the address, I get an error:

invalid parameter "xxx.xxx.xxx.xxx:8080" in /etc/nginx/conf.d/default.conf:2

Here is the default.conf :

default.conf

upstream backend_upstream {
  server xxx.xxx.xxx.xxx:8080; //Скрыл ip port :)
}

server {
  listen 80;
  server_name _ samplename;

  root /app/dist;

  proxy_set_header Host $http_host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

  location ~ (.*\.js\.map|.*.css.map) {
    return 404;
  }

  location / {
    add_header Cache-Control "no-cache";
    try_files $uri /index.html;
  }

  location @backend {
    proxy_pass http://backend_upstream;
  }

  location /api {
    try_files $uri @backend;
  }

  location /images/ {
    root /app/public;
  }

  location /rails {
    proxy_pass http://backend_upstream;
  }
}

How to set IP address of vps server for forwarding?

Answer 1
