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.

any idea why I cannot connect to AWS? This is a requirement of the project. I have loaded the certs and failed to connect to my AWS account. I have used these same certs from my local PC and made a connection and could publish to my AWS account as shown above. This indicates teh host name and certs are correct. Can someone point me to anyone who can use the DA16200 and connect to AWS using TLS.
