Summary:

As Amazon announced, AWS Signature version 2 will be turned off for Amazon S3 on 24th June, 2019. After that, Amazon S3 will only accept requests that are signed using Signature Version 4 (see this article for detail). 

Some of our products currently use Signature Version 2 for Amazon S3 API request authentication and won't be able to connect to Amazon S3. We will provide a patch which moves to using a Signature Version 4. See following tables for our products affected by this change and the solution/workaround.
