Unable to access S3 buckets in eu-central-1. Support signature version AWS4-HMAC-SHA256

06b3807 created the issue

When trying to access a S3 bucket from eu-central-1 (Frankfurt region), I get this error message:

The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256. Please contact your web hosting service provider for assistance.

Buckets from eu-west-1 (Ireland region) can be accessed without any problems.

I'm ranking this issue as a defect, because the current changelog states, that eu-central-1 should be supported:

• [Feature] Add support for buckets in region eu-central-1 (Frankfurt) (S3)

Unfortunately I couldn't find a trac ticket for this feature enhancement.

Version currently in use: Version 4.5.3 (15584)
