Boto [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed while connecting to S3

I am trying to connect to S3 using boto, but it seems to fail. I've tried some workarounds, but they don't seem to work. Can anyone please help me with this. Below is the code.

import boto

if not boto.config.has_section('Credentials'):
    boto.config.add_section('Credentials')
boto.config.set('Credentials', 'aws_access_key_id', AWS_KEY)
boto.config.set('Credentials', 'aws_secret_access_key', AWS_SECRET_KEY)
if not boto.config.has_section('Boto'):
    boto.config.add_section('Boto')
    boto.config.set('Boto', 'https_validate_certificates', 'False')
    boto.config.add_section('aws info')
    boto.config.set('aws info','aws_validate_certs','False')



s3 = boto.connect_s3(validate_certs=False)
bucket = s3.get_bucket(Bucket_NAME)
