Hi @Daniel-Git-Hub ,

Thank you very much for using AWS IoT Arduino Yun SDK!

As the initial debugging step, can you go ahead and verify the integrity of your connectivity information and credentials using another MQTT client, e.g., MQTT.fx, and see if you can connect?

Please let us know how it goes.

Thanks,
Liusu

thanks yes I can connect to that.
But I fully reset it (using a seeduino) and then re uploaded everything and set it up again
and I could connect using the default MQTT client
