AMAZON-S3 not Connecting MFT 10.7

Using version 10.7

cant connect to S3 bucket at all. keep getting error message:

Connection unsuccessful.
Amazon S3 Exception:Access Denied

i know everything is correct because i have another process outside of MFT that works fine with all the credentials i am passing in. Anyone have any experience connecting to AWS with the new MFT 10.7 UI?
