mqtt_connect fails with error -95 aws_fota

[lecozahu]

Hi !

I am working on aws_fota, with a nrf9160 dk, sdk 1.3.0. When I try to connect in mqtt, I get my IPv4 address I get the following message: ERROR - mqtt_connect -95.
When I try to debug myself, I notice that my error appears on line 97 :     ret = connect(client->transport.tls.sock, client->broker, peer_addr_size); 

of the mqtt_transport_socket_tls.c file within its mqtt_client_tls_connect () function.

could you help me ? thanks in advance

I took the first RSA 2048 certificate (I'm not sure which one exactly to take) but it still doesn't work. I still get the same error...

I did not modify the variable: CONFIG_CLOUD_CERT_SEC_TAG. Could this be the explanation?

That should not be the problem, as I did not modify it either and successfully established a connection. 

However, I managed to get the -95 error by using the wrong certificates (as you did previously), so I just want to ensure that your certificates are correct:

CLOUD_CLIENT_PRIVATE_KEY contains the <unique_id>-private.pem

CLOUD_CLIENT_PUBLIC_CERTIFICATE contains the  <unique_id>-certificate.pem

CLOUD_CA_CERTIFICATE contains AmazonRootCA1.pem

Is this your current certificates.h configuration? 

You have probably followed the readme for the sample, but make sure that every step is correct.

Indeed, I did not take the correct amazon root certificate. I can now connect.

thanks a lot for your help!
