Elastic Beanstalk Worker SQS daemon receiving a 504 gateway timeout after 1 minute

Question

I have a worker from an elastic beanstalk that can only run one task at a time, and it takes some time (from a few minutes to, hopefully, less than 30 minutes), so I queue my SQS tasks.

In my working configuration, I have:

HTTP connections: 1
Visibility timeout: 3600
Error visibility timeout: 300

(On "Advanced")
Inactivity timeout: 1800

The problem is that there seems to be a 1 minute timeout (on nginx?), Which cancels the "idle timeout", returning 504 (gateway timeout).

This is what I can find in the aws-sqsd.log file:
