I also had this problem, and I think it was because

This latest signature version is supported in all regions and any new regions after January 30, 2014 will support only Signature Version 4.

That includes eu-central-1 and others https://docs.aws.amazon.com/general/latest/gr/signature-version-2.html

But knox does not support it. Automattic/knox#254

I replaced it with the official aws-sdk here: keystonejs/keystone-storage-adapter-s3#15.

Also, switching to a different region

This issue was resolved in the keystone-storage-adapter-s3 v2.0.0 release, which replaces the unmaintained Knox library with the official AWS JavaScript SDK.
