Worked fine yesterday. I can package the game anyway but it fails when i try to upload it to iconnect.
Provisioning and code signing issues have always been somewhat of a pain. A build that worked yesterday can commonly not work the next. I would suggest building/deploying from Xcode as at is generally more verbose about issues that the UE editor. Likely it will give you the same errors but from those errors/warnings you can search for common solutions. What is the error/warning you are receiving when uploading to iTunesConnect?
I had the same issue. For me it turned out that I was using not the lastest version of OSX but the latest version of unreal. Due to the corporate software lock down I can’t updated to the latest OSX so I went to a previous version of unreal and everything worked fine. To be specific I was using OSX El capitan and 4.14 which caused issues. 4.12 works fine.
