Boto [ssl: Certificate_verify_failed] Certificate Verify Failed While Connecting To S3
Solution 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
:
importbotoconn= 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
Solution 2:
In boto3, if you are using the s3 client, use verify=False when creating the s3 client. For eg:
s3 = boto3.client('s3', verify=False)
As mentioned on boto3 documentation, this only turns off validation of SSL certificates. SSL will still be used (unless use_ssl is False), but SSL certificates will not be verified.

Solution 3:
I found a way,
used is_secure=False
in connect_s3()
.
Solution 4:
I encounter this problem, too. My environment is Ubuntu 15.04, Python 2.7.9 and Boto 2.38.0.
Setting the argument validate_certs=False doesn't make it work with the HTTPS connection without valid certificate. After reading the code of boto, I found that it's a behavior of Python's ssl modules. Then I found a solution here: "SSL: CERTIFICATE_VERIFY_FAILED" Error. And the solution does work!!!.
Solution 5:
add verify=False
boto3.resource(
"s3",
endpoint_url=<URL>,
aws_access_key_id=<ID>,
aws_secret_access_key=<Key>,
verify=False
)
