Hi, I hit this a few months ago. It works on us-east-1 because V2 is still enabled on regions created before Jan 30 2014. (I think general rule of thumb is it works in US regions only)

- See the second “Note” in [Authenticating Requests (AWS Signature Version 4) - Amazon Simple Storage Service](https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html)

I run FDB in a wrapper service, in non-US deployments I configured it to take the backup locally, then the wrapper service zips the backup files and uploads it to S3.
