Describe the bug

I can´t use WebSockets with Async_WebServer_Teensy41.

I adopted a Sketch from ESP32 where it works well.

With Teensy 4.1 the Connection establishes but send no Data to the Client (HRESULT: 0x80072F78).

Im using Windows10, "Websocket Debug Tools", Wireshark

Arduino IDE version 1.8.19
Teensyduino Core v1.58 beta3
QNEthernet library version v0.17.0

Steps to Reproduce

I used Async_AdvancedWebServer Example
and added:

AsyncWebSocket ws("/ws");

void onWsEvent(AsyncWebSocket *server, AsyncWebSocketClient *WS_Client, AwsEventType type, void *arg, uint8_t *data, size_t len) {

	if (type == WS_EVT_CONNECT) {

		Serial.println("Websocket client connection received");
		WS_Client->text("Hello from ESP32 Server");
	} else if (type == WS_EVT_DISCONNECT) {
		Serial.println("Client disconnected");

	}
}`

In SETUP:

ws.onEvent(onWsEvent);
server.addHandler(&ws);`

In LOOP:

if (millis() > timer + 5000) {
	ws.textAll(String(millis() / 1000));
	timer = millis();
}

Expected behavior

The Server should send back "Hello from Teensy 4.1 Server".
Every 5s the Server should send millis() / 1000.

Actual behavior

With "Websocket Debug Tools" I get (HRESULT: 0x80072F78)
Using Wireshark it seems the OPCODE for Websocket Connection is Wrong.

Hi! Would it be possible to modify this library to work with an ESP32 Coprocessor running on WiFiNINA? I am able to find the general WiFi library for WiFiNINA without Async capabilities (https://github.com/khoih-prog/WiFiWebServer), as well as this current Async library without WifiNINA, but not both together. Thanks for your help!
