aws-iot with esp8266 error

[ashwanipal01]

please help me on connecting with aws iot services with esp8266 12e. i am using example aws-mqtt-websocket example not able to connect with dashboard of aws iot the code is as follow and the error i get is (please start sntp first ! error connection to the websocket server)

I am having the same issue: "Please start SNTP first"

[moodgorning]

put configTime(3 * 3600, 0, "pool.ntp.org", "time.nist.gov"); in your setup to get rid of the Please start sntp first message, It is however not going to solve your problem. The sntp message can be ignored
