Hello,
I am aiming to make a post request to trigger a IFTTT webhook action.
I am using the MKR1010 board.
I am able to connect to the network and turn the connected LED on and off using the cloud integration.
The code is as follows, but doesn't trigger the web hook. I can manually paste the web address in a browser and this does trigger the web hook.
The key has been replaced in the below code with a dummy value.
Does anybody know why this is not triggering the web hook? / Can you explain why the post request is not being made. I don't even really need to read the response from the server as long as it is sent.
Thank you

// Initialize serial and wait for port to open:
Serial.begin(9600);
