I am submitting an iOS app to the App Store using Application Loader, however, it never gets past the \"Sending API usage to iTunes Connect\" stage. There i
I had my DNS set up to Google DNS. I removed the DNS settings and it worked for me.
I had this problem when behind a firewall.
I got around it by going to Xcode > Contents > Applications > Application Loader > Contents > MacOS > itms > java > lib - Open net.properties with TextEdit and change the line
# https.proxyPort=443
to https.proxyPort=80
