My Game was rejected by Apple cause of IPv6

Hi, there:
My Game was rejected by Apple cause of IPv6 network

, and I know why.
I’ve setup an IPv6 Dev Environment via [Apple Official Document][2].
And I’ve test our gaming system, which is made up of two protocols : HTTP(s) and UDP( UE4 GameServer ).
The HTTP part pass the testing of IPv6 Dev Env, which is solved by DNS( http(s)://xxx.xxx.xxx ) easily.
But I don’t know how to Open Level via DNS for UE4 to Client Travel.
What’s the form of url used by UE4? For Example : I have an url which is “web1.dragonhero.gamagic.com” where direct to the UE4 Game Server. And I can ping6 this in the IPv6 Dev Env.
How do i input the url for “Open” Command?
I’ve tried “open [url]” and “open url”, and both can’t work.

Best Regards.

p.s. : My question is simple, “how to connect to the ue4 dedicated game server via domain?”

Hi there, we’re having the same issue since long time ago, is there any update about that?. We need Apple to approve our test flight, i know that Apple can allow some exeptions, but we dont know how to handle it.
