im trying to update ThingSpeak from a SIM808 but I'm getting a network error. Please check below and let me know if there is anything wrong in my methodology.
I'm using terminal.exe to send commands via RS232.

Note: while I'm typing in the browser url box, https://api.thingspeak.com/update?api_key=MY_KEY&field1=VALUE, I can update my field. I can make calls, send SMS. I have an internet pack.
