'How to connect AWS IOT by using AT Command (Sim7020C)

Does anyone know how to use AT Command to connect AWS IOT(Sim7020C)?

It's my log below, I have tried so many times and all responses are OK. So I really can't tell what's wrong with my commands... I think something went wrong in Certification step, but I'm not sure
