Question NodeJS Websocket Nginx with process.env.PORT?

[oreoneo]

Server operating system version

idk

Plesk version and microupdate number

idk

Hello,

since Nodejs gets a port from passenger, I wanted to ask how I can use it with a websocket, because a websocket requires additional settings for nginx with a fixed port. Currently I have this in nginx. (Just wanted to say that the server does not belong to me directly, so I host with a web hosting service, therefore all "additional Nginx settings" must be made by a supporter and i cant see the versions)

location /ws {
proxy_pass http://localhost:3009/;
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;
}

Hi, yes I had already done that and with the websocket everything works so I can connect and send things etc. I just wanted to know if I can somehow take the passenger port with nginx or have to take a fixed port, because other customers of the hoster of course also use the ports and I don't want to get in the way but it also could be that passenger assigns the port to someone else and then I would have go to support and have the nginx config rewritten to another port before I can get it online again.
