nx_dns_host_by_name_get returns 0xA3(163-decimal).

Hi in MQTT example I am trying to resolved DNS for time.google.com and my AWS thing link.

For first address nx_dns_host_by_name_get  gives ok response . But for second Address it gives error 0xA3. I cant find description for the error . AWS link is ok because if it is executed first it gives on DNS.
