ESP32-CAM SSL error

[kahlenberg]

Hi,
I have a ESP32-CAM modul and I am trying to use Telegrom bot.
For text messages or "basic" things it is working, it sends message to my mobile phone.
But when I want to take a photo esp32 board says invalid SSL error.
I am also using deep sleep function. My esp32 board first wakes up and cheks telegram if new messages exist. If ther is any new message, it sends the response back. But taking photo with camera isn't working due to SSL error:

Code: Select all

String BOTtoken = "XX--XX--XX";
WiFiClientSecure secureClientTCP;
UniversalTelegramBot bot(BOTtoken, secureClientTCP);

void setup () {
// WiFi settings
// Serial settings
  int numNewMessages = bot.getUpdates(bot.last_message_received + 1);
  ESP_LOGI(TAG, "Number of messages: %d", numNewMessages);
  while (numNewMessages) {
    ESP_LOGI(TAG, "Got response....%d", numNewMessages);
    handleNewMessages(numNewMessages);
    numNewMessages = bot.getUpdates(bot.last_message_received + 1);
  }

  ESP_LOGI(TAG, "Sleeping..");
  esp_deep_sleep_start();
}
