nRF9160 Modem Firmware 1.3.0 fails in LTE connection

Hi, 

I was using NCS 1.5.0 and Modem firmware 1.2.3. 

I have latest DK of nRF9160. 

It was running properly without issue specially LTE connection. 

But after I migrated from 1.2.3 to 1.3.0 modem firmware, I have noticed LTE connection failure sometimes. 

I get below print on pc terminal 

LTE Link Connecting ..

After that I don't get anything. Which means it fails to connect with LTE. 

When this issue happens I try to reset nRF9160 through  "nrfjprog --reset" but after system reset also I get same issue. 

Issue gets resolved only after I do power off and power on.  

Regards,

Smitesh Mali
