I developed a product on 9160 using the ncs1.9.0 SDK and the 1.3.2 modem firmware. When debugging, I found a problem. That is, when connecting to a domain name, the modem returned the error of domain name resolution failure. However, using the same hardware device, running the ncs1.2.0 SDK can connect to this address, that is, there is no problem with the network and the background domain name, Then why is there an error on ncs1.9.0? This is the modem trace I captured.
