Not able to connect to the HTTPS API using an A7670C with ESP32

There could be several reasons why you're unable to connect to the HTTPS API using an A7670C with ESP32. Here are some common issues and troubleshooting steps:

Network Connection: Ensure that your ESP32 is properly connected to the network. Check the Wi-Fi status using WiFi.status() to confirm it's connected.

SSL/TLS Configuration: Verify that your SSL/TLS configuration is correct. This includes having the correct certificates and keys2. Make sure the certificates are properly installed and accessible by your ESP32.

API Endpoint: Double-check the API endpoint URL and ensure it's correct. Sometimes, a typo in the URL can cause connection issues.

Firewall/Router Settings: Ensure that your firewall or router settings are not blocking the HTTPS connection. Some routers have settings that can interfere with SSL/TLS traffic.

Library Dependencies: Make sure you have the necessary libraries installed and correctly configured, such as TinyGSM and ESP_SSLClient for handling HTTPS connections.

Power Supply: Ensure that the A7670C module is receiving a stable power supply. Insufficient power can cause connectivity issues.

Error Handling: Implement robust error handling in your code to catch and diagnose any issues during the connection attempt.

Debugging: Use debugging tools and logs to trace the connection process and identify where it might be failing.
