Nest.js app in cluster mode with NGINX or manually sticky sessions(farmhash)

[Bubuioc]

Hey, i posted some days ago a question about the Nest.js cluster mode and sticky session, but i got no answer.
I need this for my work project and have no senior that can help me with advice or configuration and i have some days left to implement it.
I found on the net this implementation with farmhash medium post it seems to work, but I don't know how good is this for production, dev(not local) server.
So i decided to implement NGINX.I have installed it and configured but still get the Session ID unknown error.I saw the example with multiple nodes(docker containers) and i think this is the problem because as I said above I have single container of my Nest app running in cluster mode.

# Reference: https://www.nginx.com/resources/wiki/start/topics/examples/full/

worker_processes 12; # 12 worker processes = 12 threads running my nest app

events {
  worker_connections 1024;
}

http {
  server {
    listen 80;
    server_name my.ngrok.domain.dev; #Client access my app with ngrok dev domain, i forward the nginx port 80 for this domain not the app port

    location / {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $host;

      proxy_pass http://nodes;

      # enable WebSockets
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }
  }

  upstream nodes {
    # enable sticky session with either "hash" (uses the complete IP address)
    hash $remote_addr consistent;
    # or "ip_hash" (uses the first three octets of the client IPv4 address, or the entire IPv6 address)
    # ip_hash;
    # or "sticky" (needs commercial subscription)
    # sticky cookie srv_id expires=1h domain=.example.com path=/;
    
    server 127.0.0.1:3000; #My app runs on 3000 port
  }
}

The question is did i configure NGINX wrong and this is because i still get the Session ID unknown or it can be used only for multiple nodes(containers) not for one app running in cluster mode.Or the thing with farmhash from the blog above is good choise for a production for a +- 50 users.
Thanks for help already.
