        Hello I'm Ahmet, from Turkey.

         

        Here any ISP give IPv6 adress but Apple want to test game only IPv6 network. So we can't test our game at all stages person from apple can't connect our server. At IPv4 there is any problem. Game developing in Unity.

         

        What can we do for this problem?

         

        Thanks for your help and understanding.

          You can set up an IPv6 test network per item #1 in my Supporting IPv6-only Networks pinned post.

          Having said that, I think it’s unlikely that this is caused by an IPv6 problem.  Presumably your server is on the public Internet?  Can you post the DNS name and port number here?

              IPv4 : 34.242.141.209

              IPv6 : 2a05:d018:64e:9b00:1004:be60:a435:6ffd

               

              Port : 50900

               

              I can connect to server from my IPhone 11 with IPv4, I can connect to server from other VPS with IPv6.

               

              But when I send game to rewiew apple staff can't connect anytime

               

              And if I do #1 on your post, network is unreachable from mu phone

                  Port : 50900

                  Is that UDP or TCP?

                      Both are opened but we use reliale UDP network system.

                          Interesting.  I tried this from inside Apple and I wasn’t able to connection to either address:

                          $ telnet 34.242.141.209 50900
                          Trying 34.242.141.209...
                          telnet: connect to address 34.242.141.209: Connection refused
                          telnet: Unable to connect to remote host
                          $ telnet 2a05:d018:64e:9b00:1004:be60:a435:6ffd 50900
                          Trying 2a05:d018:64e:9b00:1004:be60:a435:6ffd...
                          telnet: connect to address 2a05:d018:64e:9b00:1004:be60:a435:6ffd: Connection refused
                          telnet: Unable to connect to remote host

                          I also tried it from home and got the same result:

                          $ telnet 34.242.141.209 50900
                          Trying 34.242.141.209...
                          telnet: connect to address 34.242.141.209: Connection refused
                          telnet: Unable to connect to remote host

                          [I can’t try IPv6 from home because my IPv6 is playing up at the moment )-: ]

                              It is weird.

                               

                              But we are connecting to server from PC, Android and My IPhone 11 IOS 13.3.1

                               

                              But today; apple staff still can't connect to server

                               

                              We tested IPhone 11, 7, 8 and 8 plus all works.

                               

                              Can you test to look "34.242.141.209", can you see xammp page here?

                               

                              And is this possible to add you as Test Flight user for looking to connection?

                                  My advice here is that you sign up to a VPN service that has egress points in various countries around the world and use that to check the availability of your service.

                                      Connecting from client is success with same port. Client from PC, Android and my IPhone 11.

                                      Maybe ICMP requests are closed at server side.

                                        I think problem is not NetworkLibrary because I tested 2 library and same result.
                                        I tested 2 server in microsoft and aws so problem is not server.
                                        I and apple staff use same device same IOS version so problem is not ciient device.
                                        Yesterday we realized some android users have same problem so problem is not ios and android client.

                                         

                                        But what is problem I don't know Connection error is network unreachable but how is it possible with same models of IPhone 11 and same IOS version 13.4
