After adding Load Balancer, my NodeJs server is not receiving any handshakes and got’s rejected automatically. The question i have is, do i need to add some specific http/tcp redirect rule to that Load Balancer in order to receive calls on droplets?

Hello, @bachinadiradze

May I ask if you’ve opened all the needed ports on the Load Balancer? You can check all the ports you need/use and make sure they’re open on the Load Balancer as well.

I’m having a similar issue with NGINX

Did you solve this? I have thesame problem.

  • Hey i did resolve the issue back then. If i remember correctly it wa both and Nginix issue and i added some of the proxy headers which fixed nginx side:

    server {
            listen 80;
            listen [::]:80;
            location / {
                proxy_pass http://localhost:8080;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_set_header Host $host;

    And socket side i added:

    // library ->
    this._socket = io("/", {
       transports: ['websocket', 'pooling'] // this part

    Hope it helps. I would go for socket fix first if it won’t do it then you can try nginx one.

    Good luck :)
