**Description**  
Hi  
I will try apple review with my zoom-sdk-ios app  
Thus, [apple review guidelin](https://developer.apple.com/app-store/review/guidelines/) said that

> `2.5.5 Apps must be fully functional on IPv6-only networks.`

then, i try my zoom-sdk-ios app to execute in the ipv6 network  
i met error of API authentication task failed, error code: 5

I think that The Zoom Server does not correspond to ipv6 , is it correct?

**Which version?**

4.3.47201.0322

**To Reproduce(If applicable)**  
i setting iOS to use ipv6 only at network setting in iOS  
then, My server is OK ,becouse my server set ipv6 network

**Smartphone (please complete the following information):**

- Device: iPadPro(first generation)
- OS: [iOS12.3.1]

Hi,  
Thanks for your patient. We have tried our SDK with IPv6 environment and we did not find any issues. Our SDK support IPv6 environment. Could you have a try with our official Zoom client and see if our Zoom client works?

Thanks!
