I will try this right away. But i have an another question.

If i want to publish my web sites (more than one. they are subdomains and about 4 or 5 pcs), do i need conf file for each web sites?

Here’s an example of nginx config to reverse proxy a node-red server (websocket support)

server {
  listen 80;
  server_name your_server_name;

  access_log /var/log/nginx/access.log;

  location / {
    proxy_pass http://localhost:1880;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
