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

Question

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)

Answer 1

Probably your bucket name contains a dot, that's why ssl certificate verification fails. This is quite a frequent problem, see this github issue for example.

Don't use an insecure connection (is_secure=False), instead use OrdinaryCallingFormat:

import boto
conn = boto.s3.connect_to_region('eu-west-1', calling_format=boto.s3.connection.OrdinaryCallingFormat())
bucket = conn.get_bucket(your_bucket)

You probably need to update your AWS Region, e.g. us-east-1
