I'm using CytronWiFiShield for my Arduino project and trying to run the https client example but failed.

Serial Output:
Start wifi connection
Connected to: ABC Unifi
IP address:
Connecting to
Failed to connect to server.

Is there any extra step to do for https requests? (eg. cert)

Which version of shield you are using, version 1 or 2? Please use CytronWiFiDemo in examples to check your shield AT version.

You can try this user manual on firmware installation for SSL support. Please complete all the steps in part 8 before proceed to use this shield with Arduino.

Note: Above all, please use CytronWiFiDemo to verify your valid connection to servers before doing firmware installation, the sketch uses http server.
