Getting Exception (3) while trying to send data

Hardware: ESP8266

Description

I am getting Exception (3) when I try to send data to a AWS server. I have made sure that my credentials are ok, so I have to ask you for help. I get this exception after about two tries to send the data (two loops) and then my program ends.

Below is my stack trace.
