I recently published a game on the appstore. Unfortunately, the during the App Review they can't connect to my server. And I fail to understand why. The game supports both ipv4 and ipv6 and is running live since 8 months on Android/Windows with an average of 200~ concurrent players without any issue. I ported it on iOS (it's written in C++ and use raknet for the socket) and It's working well on my Apple devices : Ipad, iphone 5C, iphone SE 2020, and I even tested the game with 13 different Iphone devices on Amazon Device Farm and the multiplayer worked.The game uses only UDP sockets to connect to a server on port 53487(ipv4) and 53488(ipv6). I didn't setup DNS64/NAT64 because it works without it on other platforms.They is no way to fix this issue, because I just can't reproduce the issue the App Reviewers are facing and after one week of testing every situation possible to find why they can't connect, I'm out of ideas and I'm starting to think that maybe the issue doesn't come from me but from Apple's firewall or something specific to App Reviewers ? (such as blocked port, permissions...?)I would really appreciate some help.Thanks
