When using S3 with its own domain, "." Is entered in the bucket name, but at this time, SSL connection seems to be no longer supported.
At this time, if you connect to S3 with boto, an error around SSL will appear.
Solved with the following code.
from boto import s3 from boto.s3.connection import OrdinaryCallingFormat conn = s3.connect_to_region('eu-central-1', calling_format=OrdinaryCallingFormat())
