When you created the mobile provision you would select more than one certificate that it works with. More than likely you didn’t do that. It’s possible that something got changed after the code sign, but before you uploaded it. That has happened in the past, but I thought we had gotten all of those bugs resolved.
I also just did a sanity check for 4.10.3 with one of our content-only projects and it did upload properly. What I noticed tho is my code sign on PC took almost 30 seconds while yours took about 2 seconds which seems a little odd. I’m going to update to 4.10.4 since that is what the log is from and see if I get similar results.
