Getting “Cannot verify client. (3000)” when trying to upload archive from Xcode to itunesConnect

Question

Just updated to Xcode 7.1 and getting this error. Was able to upload fine using 7.0.1

Answer 1

For what it's worth: I got this error when my startdisk was almost full (less than a few hundred MB left).

Cleaning up some space and re-submitting resolved this issue.
