Issue #216 new
Davide Mendolia created an issue

AWS4-HMAC-SHA256, also known as "V4," is one of two authentication schemes in S3.

US-Standard, and many -- but not all -- other regions, also support the other, older scheme, V2.

Frankfurt was introduced late in 2014, it does not support V2. explains how to enable V4 in the various SDKs, assuming you are using an SDK that has that capability.

I would speculate that some older versions of the SDKs might not support this option, so if the above doesn't help, you may need a newer release of the SDK you are using.
