Setting up a ESP32Cam in https mode keep getting stuck on it's final step. In http mode all is working as it should. When building the https sketch (below) i am not getting the needed return messages: 'Connection opened' and 'Websocket Connected'
Testing it on a mac, having installed openssl, nodejs, npm correctly, getting everything running without errors. Connecting a CP2102 to the ESP32Cam. What am i missing?

@bananaboat , your topic has been moved to a section of the forum where it hopefully get a better exposure.
Are you receiving any events? I recommend you log any unhandled events.
Shouldn't you set 'isWebSocketConnected' to 'true' in here somewhere?
It says in the 4th block
void onEventsCallback(WebsocketsEvent event, String data){
if(event == WebsocketsEvent::ConnectionOpened){
Serial.println("Connection Opened");
isWebSocketConnected = true;
I have been testing this throughout and it seems to be a ws / wss protocol issue.
Testing the none https version WITHOUT ws worked! WITH the ws protocol on the other hand did not.
The none https version code:
#include "esp_camera.h"
#include <WiFi.h>
#include <ArduinoWebsockets.h>
#define CAMERA_MODEL_AI_THINKER
#include "camera_pins.h"
//part8
const char* ssid = "hello";
const char* password = "1234";
// const char* websocket_server_host = "ws://192.168.2.3"; // does NOT get WebSocket connection
const char* websocket_server_host = "192.168.2.3"; // DOES get websocket connection!
const uint16_t websocket_server_port = 8888;
using namespace websockets;
WebsocketsClient client;
bool isWebSocketConnected;
void onEventsCallback(WebsocketsEvent event, String data){
if(event == WebsocketsEvent::ConnectionOpened){
Serial.println("Connection Opened");
isWebSocketConnected = true;
}else if(event == WebsocketsEvent::ConnectionClosed){
Serial.println("Connection Closed");
isWebSocketConnected = false;
webSocketConnect();
}
}
void setup() {
isWebSocketConnected = false;
