Answer 1

I have been using Django, and I had to add these extra config variables to make this work. (in addition to settings mentioned in https://simpleisbetterthancomplex.com/tutorial/2017/08/01/how-to-setup-amazon-s3-in-a-django-project.html).

AWS_S3_REGION_NAME = "ap-south-1"

Or previous to boto3 version 1.4.4:

AWS_S3_REGION_NAME = "ap-south-1"

AWS_S3_SIGNATURE_VERSION = "s3v4"
