Hi,
I've tried complete tutorial from eclipse documentation on eclipse github io(I think maybe it's outdated, I noticed some differences between tutorial and current version...), but when I try to connect to AWS IoT, i got this error:

I think I'm sure I set correctly port (8883) and mqtts://, Lwt.retain is set to false, private key is converted to the PKCS8 format.
I use Kura v. 5.1.2.
Screenshots below shows my settings:

Hello,
it seems like the connection has been dropped at the AWS side.
What is the configuration of the thing in AWS?

Best regards,
Matteo

Hi,
thanks for your answer. I just forgot to attach policy to certificate of my device... Now it works fine.

Best regards,
Krzysztof
