BL475E-IOTA library fails while sending data

[PTeja.1]

BL475E-IOTA library fails while sending data to the MQTT broker. I see the below prints on the console. I'm using the default STM32 library for AWS. Can anyone please let me know why I'm seeing these errors. Thank you.

Hello

When does this happen ?

It looks like the remote server is closing the connection.

Did you enter correct configuration ? (endpoint address, thing name, certificates)

Hi @PTeja.1​  were you able to connect BL475E-IOTA to AWS ?
