MQTT Sample code is not connecting

[vkadal]

The sample code at ncs/nrf/samples/nrf9160/mqtt_simple is not connecting. I dod not make any changes to the ode. I am using NB-IoT. LTE is connected. The link monitor, LTE is in green. The error code is ERROR: mqtt_connect -60

Kindly advice to resolve this

Cloudmqtt accepts data in JSON format. So I need to check this  point

LTE Link Connected!

Could you configuring your project with "CONFIG_NRF_CLOUD_IPV6=y" set and see if this helps?

 

Kind regards,

OK, will  do that. The code given by you works and connects to test.Mosquito.com

Still the same error.

Have you checked with your mqtt provider that they support ipv6?

 

Kind regards,

What is CloudMQTT

CloudMQTT are managed Mosquitto servers in the cloud which provides lightweight methods of carrying out messaging using a publish/subscribe message queueing model.  -- This I have found in their website. For more details, please check  at https://www.cloudmqtt.com/docs/faq.html
