SignatureDoesNotMatch - Amazon s3 can't upload image

Question

Error:

Excon::Error::NotFound (Expected(200) <=> Actual(404 Not Found)

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

I have developed uploading images via carrierwave via s3. But this error happens and aws access id and secret key are not wrong. And s3 settings is currently in public.

Answer 1

The region setting was wrong. After I update, that would work.
