AWS PHP SDK failure when attempting to admin Shipper

Would like to know if Shipper is accessing AWS as if it is from the website or is it accessing AWS from wpmudev servers? I have an error when I try to start the admin of Shipper. See attachement.

I have a lockdown on AWS. I set the security for the bucket that only the website, in this case can directly access the bucket. If your AWS SDK for Shipper does not access AWS from the website but from one of your servers, it will not work.

So how would I identify your servers, if that is the case, otherwise what is the issue?

The identity can be an FQD ie.

Support access is enabled.
