Da16200 connecting to AWS

I have the DA16200 evaluation board. I am trying to connect to my AWS account. I have mqtt_config setup as shown below. when I try to connect I get the following message. It is crucial that I am able to connect to my AWS account using TLS and certificates. I have loaded the 3 certificates that I use to connect to my AWS account from other boards. These certificates work for all other cases.

#2 (HTTPs, CoAPs Client)
