Websocket disconnecting

 It is designated for use in
      applications expecting a status code to indicate that the
      connection was closed abnormally, e.g., without sending or
      receiving a Close control frame.

you will want to print the reason for error and the reason for disconnect respectively

    this.ws.on("close", closeMessage => {
      console.log("WEBSOCKET CLOSE", closeMessage); // 1006 WAS LOGGED
      if (this.shouldReconnect) {
        this.scheduleReconnect();
        this.stopPingTimer();
      }
    });

    this.ws.on("error", (error: any) => {
      // if (error.code === "ECONNREFUSED") return;
      console.log(`${this.nameIdentifier} WebSocket error`, error); // NOTHING WAS LOGGED
    });
