Unable to upload app to iTunes Connect - iTunes Store operation failed. Authentication timeout

Question

I\'m trying to upload my app to iTunes Connect with Xcode. I chose product > archive, choose my account, it compiles and when I try to upload it hand for a long time on:

Answer 1

In my case, The build with the same number (e.g. Version 1.0(1.6)) was already been uploaded to AppStore. I found that after logging into itunes and checked the TESTFLIGHT BUILDS -> iOS and there I saw 1.6 (Processing)

Note: 1.0 is the version number and 1.6 is build number.
