simple mqtt and mqtt publisher not working.

[Y0g1]

Hi i was trying to use simple mqtt sample provided as example with location "ncs/nrf/samples/nrf9160/mqtt_simple" the code was build and run but during lte connection it takes aroung 5-10 minutes and after that it was failed to connect with mqtt client i tried by default defined "mqtt.eclipse.org" and some other brokers but everytime gives me error 

*** Booting Zephyr OS build v2.4.0-ncs1  ***The MQTT simple sample startedLTE Link Connecting ...+CEREG: 2,"FFFE","FFFFFFFF",7,0,0,"11100000","11100000"+CEREG: 0,"FFFE","FFFFFFFF",7,0,0,"11100000","11100000"+CEREG: 2,"00D8","003AC006",9,0,0,"11100000","11100000"+CSCON: 1+CEREG: 5,"00D8","003AC006",9,,,"11100000","11100000"LTE Link Connected!IPv4 Address found 198.41.30.194ERROR: mqtt_connect -60

i search for the error it was showing timeout error but doen't help me as i didn't find to resolve it.

after this i was also trying the other sample code mqtt publisher at location "zephyr/samples/net/mqtt_publisher". the code build and programmed but after that device rebooting again and again with following error 

Non-secure callable region 0 placed in flash region 0 with size 32.

.

can you please guide me for the mqtt code. as my requirent is to publish some messages on server after regular time intervals and how to make it faster connect with lte. please reply asap.
