In the logs, the mqtt transport layer is showing socket failure due to DNS lookup failure. On the device's shell, does a dns lookup for the same host also fail? You can check the config there against the expected DNS configuration. Are there specific dns server(s) required for the network environment of the device? Are the firewall rules on the network nodes along the route allowing DNS traffic?
