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

Still getting the same error despite "unchecking" bitcode and also archiving with the bitcode under Basic Profile turned off in the info.plist.

It would only work if I used Application Loader, like this:

First, export the application Archive from Xcode's Organizer window (it saves this into a directory on the Desktop).

Then, from Xcode:

Xcode > Open Developer Tool > Application Loader

My guess is that there is a bug somewhere either with iTunes Connect back end or xCode itself.
