TM4C129ENCPDT: No communication with NTP server (time.nist.gov) - Secure IoT Gateway

Part Number: TM4C129ENCPDT

Hi,

I am currently building the "Secure IoT Gateway Reference Design for Bluetooth® Low Energy, Wi-Fi® and Sub-1 GHz Nodes", but for one reason I  have a error during the connection with the NTP server (See picture below).

The specs and devices for the gateway for this project are as follow:

I do not have communication with exosite due to this issue with NTP, the files wolfssl_tm4c_hc.aem4f and wolfssl.aem4f were created successfully and rerouted to the right location in the command line interf, exosite interf and Gateway Main_app respectively (see picture below).

  Also I am not sure if the handshake process is a "MUST" to have communication from the gateway to exosite. I could create a new ca_cert.pem and replace it for the old one, but still no communication with the NTP server. 

please if you need more information do not hesitate to contact me, 

Thank you
