We discovered one or more bugs in your app when reviewed on iPad and iPhone running iOS 10.0.3 on Wi-Fi connected to an IPv6 network.
Specifically, we found that your app displayed a network error message when the “登录” button is tapped. Please refer to the attached screenshot/s for more information.
Next Steps
Please run your app on a device while connected to an IPv6 network (all apps must support IPv6) to identify the issue(s), then revise and resubmit your app for review.
If we misunderstood the intended behavior of your app, please reply to this message in Resolution Center to provide information on how these features were intended to work.
For new apps, uninstall all previous versions of your app from a device, then install and follow the steps to reproduce the issue(s). For updates, install the new version as an update to the previous version, then follow the steps to reproduce the issue(s).

你自己有按照官方文檔測試過嗎？
重點不在於伺服器,蘋果會認為你的app應該能否透過ipv6模式去存取伺服器.
所以你可以在自己的網路中創建一個ipv6的熱點,透過這個熱點你去存取任意網路,如果可以存取,就說明支援ipv6.
將伺服器設定成網域名稱,以便可以透過ipv6存取對應的伺服器.
然後讓客戶端網域解析獲得ipv6位址來存取.
curl最新版本是支援ipv6的, coco2dx最新版本也是支援的.luasocket預設也是支援ipv6模式的.
我的同事也遇到這個問題了。
