So this just started happening now, I have no idea as to why. I needed a new Distribution certificate because my old on expired. So following the steps I created a Certificate Signing Request and submitted it to the portal.
After submitting the request comes up as 'issued' then disappears. Clicking on the 'History' tab says the request returned an Error and nothing else.
So try a different method, using Automatic Provisioning via XCode open Xcode's "Window" menu > Organizer > Devices tab > "Provisioning Profile" sidebar under Library. Check the "Automatic Device Provisioning" checkbox and click the "Refresh" button.
it says 'You don't have a distribution certificate, want to submit a request?' I say yes and nothing happens.
Then Clicking on the 'History' on iOS Provisioning profile tab says the request returned an Error again...
I actually suspect something is wrong on Apple's end here...
issue was on Apples end, now resolved
