user36882: I have hooked up an SIM900A module to my Arduino UNO and I wanted to send a GET request to my aws server for which I have created a RESTful API, the problem is that when I send a request using AT commands I get 601 error code. But I am easily able to connect to https:// www.goolge.com and get the HTML page. I have seen some other links which are very much technical for me like https://stackoverflow.com/questions/39177095/unable-to-invoke-aws-api-gateway-get-url-with-gprs-connection and https://electronics.stackexchange.com/questions/266974/testing-a-connection-to-a-tcp-socket-through-sim5320a-cellular-module.
I want to know if SIM900A even support connections to HTTPS and if yes, how can I connect to my aws server. I kind of a noob in networking, so sorry if I cannot elaborate on details. I have read somewhere online that SIM900A only supports half https, I don't know what that means, any help/advice would be helpful.
AT commands I used
AT
AT+CGATT = 1
AT+SAPBR=3,1,"CONTYPE","GPRS"
AT+SAPBR=3,1,"APN","www"
AT+SAPBR=1,1
AT+SAPBR=2,1
AT+HTTPSSL=1
AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL","https://www.google.gom"
AT+HTTPACTION=0
AT+HTTPREAD

user50972: When you use https, you must not use: 
AT+HTTPPARA="URL","https://www.google.gom"

You must use:
AT+HTTPPARA="URL","www.google.gom"
