We are trying to connect MQTT over IPv6 with nrf9160dk and custom board. We are using mqtt_simple sample.
Software NCS version: NCS main (latest)
Changes in the code: MQTT Broker is AWS
As seen in the below log, we are able to resolve the IPv6 address and not able to connect with mqtt_connect.
Any help is highly appreciated!
