Keep Trying!

It might be DNS Pollutionissue, at least for my case (in China).
这可能是DNS 污染问题，至少对我而言（在china）。
If you're also in China or some places that has DNS Pollution issue, you might solve this by modifying the DNS (to 8.8.8.8as an example) for your Mac as well.
如果您也在china或某些有 DNS 污染问题的地方，您也可以通过修改8.8.8.8Mac的 DNS（例如）来解决此问题。
I got this error inner my iPad App & this happens randomly, it's such boring. Keep trying is not a good solution for me, though it might works somehow. Finally, I just changed my Wi-Fi DNS and no more error now. Steps:
我的 iPad 应用程序内部出现此错误，这是随机发生的，太无聊了。继续尝试对我来说不是一个好的解决方案，尽管它可能以某种方式起作用。最后，我刚刚更改了我的 Wi-Fi DNS，现在没有更多错误。脚步：
- Your device, Settings/Wi-Fi
- Choose connected Wi-Fi pot
- Press DHCP/DNS
- Set to
8.8.8.8
- 您的设备、设置/Wi-Fi
- 选择已连接的 Wi-Fi 锅
- 按 DHCP/DNS
- 设置
8.8.8.8

I faced the same problem, it turned out to be VPN related. If you are testing on a device against a corporate network, chances are your Mac has proper VPN set up, but your phone does not. Connect phone to the corporate VPNfor your apps deployed to device to see corporate servers.
我遇到了同样的问题，原来是 VPN 相关的。如果您正在针对公司网络的设备上进行测试，很可能您的 Mac 设置了正确的 VPN，但您的手机没有。将手机连接到公司 VPN，以便部署到设备的应用程序查看公司服务器。

- Change DNS to 8.8.8.8 and 4.2.2.2
- Open net.properties and change "# https.proxyPort=443" to "https.proxyPort=80". You can find net.properties here /Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/MacOS/itms/java/lib/net.properties
- Open Application Loader->Preferences->Advanced and uncheck Signiant and Aspera. Make sure DAV is checked.
- 将 DNS 更改为 8.8.8.8 和 4.2.2.2
- 打开 net.properties 并将“# https.proxyPort=443”更改为“https.proxyPort=80”。您可以在这里找到 net.properties /Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/MacOS/itms/java/lib/net.properties
- 打开 Application Loader->Preferences->Advanced 并取消选中 Signiant 和 Aspera。确保选中 DAV。
Thants all. Now you can submit app using both application loader and Xcode.
