Aws signature does not match

[sayginburak]

Hello,

I deployed to heroku and enter my s3, ses and smtp credentials. But when I try to upload a picture app couldn't upload to s3. Aws gives this error.

\nSignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing method.......

and this goes on.

What may be the problem here?
