Unable to connect aws s3 bucket using boto

AWS_ACCESS_KEY_ID = '<access key>'
AWS_SECRET_ACCESS_KEY = '<my secret key>'
Bucketname = 'Bucket-name'
import boto
from boto.s3.key import Key
import boto.s3.connection
conn = boto.connect_s3(AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY,
host ='s3.ap-southeast-1.amazonaws.com',
is_secure=True, # uncommmnt if you are not using ssl
calling_format = boto.s3.connection.OrdinaryCallingFormat(),
)
bucket = conn.get_bucket(Bucketname)


Error:

please help me to solve this problem there is no problem in bucket name and access key and secret key.

Answer

You can also use the following (boto.s3.connect_to_region):

import boto
from boto.s3.key import Key
import boto.s3.connection

AWS_ACCESS_KEY_ID = '<access key>'
AWS_SECRET_ACCESS_KEY = '<my secret key>'
Bucketname = 'Bucket-name' 


conn = boto.s3.connect_to_region('ap-southeast-1',
       aws_access_key_id=AWS_ACCESS_KEY_ID,
       aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
       is_secure=True,               # uncomment if you are not using ssl
       calling_format = boto.s3.connection.OrdinaryCallingFormat(),
       )
bucket = conn.get_bucket(Bucketname)

This way you don't have to care about the 'exact' endpoint with the full hostname. And yes like @garnaat mentioned, use the latest boto API.
