Cloud MQTT example Issue

[Chris]

I follow this instruction to turn Raspberry Pi into an IPV6 router on IPV4. My raspberry pi works well after I add nameserver to /etc/resolv.conf.

But other device in my NAT network can only get 17 scores in ipv6-test.com. The DNS6 + IP4 and DNS6+IP6 are unreachable.

Under this case, the IoT Cloud MQTT example is not been able to send data to cloud. It falls in assertion failure.

Could anyone offer some suggestions?

Thanks,

Hi Chris,

The symptom you report is most often observed when a valid "global" address is not assigned to the kit (through radvd on Raspberry PI). You will observe the reason for failure would be "routing error".

If this is not reason, posting the reason for failure would help investigate the issue further.

Hope this helps!
