Why am I unable to validate iOS App Archive?

I am getting the following error on attempting to validate my app through Xcode's organizer:

I have followed all the instructions I can find trying to fix this issue but to no avail. There are dozens of other threads out there that have many suggestions.

We recently renewed for another year and have rolled over into the second. I have literally revoked and regenerated all of our certs using new keys and have updated and regenerated provisioning profiles. I have never had this much trouble getting an update for one of our apps submitted. I'm at my wits end.

I understand that this 'technically' isn't a 'programming' question at its core, but I think the spirit of this should allow the question to stand in the hopes of other developers around here having run into this. (And yes, I will also be reporting a bug to Apple.)

So, how about it... anyone out there have the magic.

You're the third+ person with the very same problem in past few hours, this is a temporary technical issue with iTunes Connect servers that should be fixed soon. Checking Apple Forums, lots of other people have had the same issue in the past couple of hours:

It seems that newly generated .mobileprovision files (since roughly several hours ago) have a different formatting then before.

When comparing mobile provisioning files that I've generated today with older ones there are some obvious differences. Theres more spacing between the elements and the private key segment is placed on one line instead of 33(?) lines like before.

Manually restoring the .mobileprovision file format to match older ones does not help to resolve the issue.

I'd suggest waiting some more, or contacting Apple's Support Team (even calling them, since they're really good at answering phone calls) to see what they say.
