my first test with boto fails with SignatureDoesNotMatch

So here is my first test for S3 buckets using boto:

import boto

user_name, access_key, secret_key = "testing-user", "xxxxxxxxxxxxx", "xxxxxxxx/xxxxxxxxxxxx/xxxxxxxxxx(xxxxx)"
conn = boto.connect_s3(access_key, secret_key)
buckets = conn.get_all_buckets()

I get the following error:

Traceback (most recent call last):
  File "test-s3.py", line 9, in <module>
    buckets = conn.get_all_buckets()
  File "xxxxxx/lib/python2.7/site-packages/boto/s3/connection.py", line 440, in get_all_buckets
    response.status, response.reason, body)
boto.exception.S3ResponseError: S3ResponseError: 403 Forbidden

How am I supposed to fix this?

Boto version is 2.38.0

Today, I saw an error response with SignatureDoesNotMatch while playing around an S3 API locally and replacing localhost with 127.0.0.1 fixed the problem in my case.

Had the same issue. In my case, my generated security key had a special character '+' in between. So I deleted my key and regenerated a new key and it worked with the new key with no '+'.
