Double connection

Hi there, I got a double connection when using this code. Is there a way to prevent this?

import { Injectable } from '@angular/core';
import { Socket } from 'ngx-socket-io';
import { AuthService } from '../auth/auth.service';
import { WSMessage } from '../dto/i-ws-message';

@Injectable({
  providedIn: 'root',
})
export class WebsocketService {
  constructor(private socket: Socket, private _auth: AuthService) {}

  receiveUpdates(channel: string) {
    return this.socket.fromEvent(channel);
  }
}

@grafixen It looks like that sample is using a Socket.IO version 2.1? Version 4.0 requires the use of Socket.IO 4.0

You are right. Downgrading ngx-socket-io to v3.2.0 seems to solve the issue. Thank you!

I am still getting the double connection issue. I’ve tried installing the versions suggested, but this does not help.
