Using S3 as file storage conflicting with SSO

We have the database parameters setup successfully to read and write to an AWS S3 bucket when we run locally, but when attempting to setup and run in the Mendix cloud, it causes the SSO to stop redirecting to our page. Any ideas on what to look for?

On the Custom Settings page it clearly says that this setting is strongly discouraged in the Mendix Cloud, so I'm not surprised this does not work.

Also, a clear error for the log file would be helpful.

Did you set up request handlers correctly for SSO?
