The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate.

Answer 1

It's been my experience that Xcode occasionally gets confused about which signing certificate to use. I got into the habit of quitting and restarting Xcode after any change to the code signing settings (and doing a clean build) to work around this problem.
