application loader stuck at "testing tcp udp connectivity"
you wont believe what I have been to so far, but to cut the story short:
The program is stuck at "testing tcp udp connectivity" when uploading an iphone app
The second solution at itunesconnect using application loader behind a firewall worked for me.
For reference:
Go to Preferences, Advanced, select DAV only.
This will use port 443 (aka HTTPS) for uploading.
Then use application loader to upload your application.
PS. For me it stayed at 0 bytes/sec for a good five minutes at the "Uploading package to the iTunes Store message", but given enough time updates at the 50% mark and then at the 100% mark. Leave it running for a good 10/15 minutes (depending on your app size) before you quit it.
那么，事实证明，该公司的网络中的端口被阻塞，回到家中，它的工作。
