Hello, I Have trouble when sending push notification to apns sandbox environment. I use dotnet 6 and use below sand box host port. const string APNS_SANDBOX_HOST = "api.sandbox.push.apple.com"; const uint APNS_SANDBOX_PORT = 443; After few minutes after publish code, below error is shown. System.Net.Http.HttpRequestException: An HTTP/2 connection could not be established because the server did not complete the HTTP/2 handshake. at System.Net.Http.HttpConnectionPool.ReturnHttp2Connection(Http2Connection connection, Boolean isNewConnection) at System.Net.Http.HttpConnectionPool.AddHttp2ConnectionAsync(HttpRequestMessage request) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.ExecutionContextCallback(Object s) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext(Thread threadPoolThread) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext() at System.Threading.Tasks.AwaitTaskContinuation.RunOrScheduleAction(IAsyncStateMachineBox box, Boolean allowInlining) at System.Threading.Tasks.Task.RunContinuations(Object continuationObject) at System.Net.Http.HttpConnectionPool.ConnectAsync(HttpRequestMessage request, Boolean async, CancellationToken cancellationToken) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext(Thread threadPoolThread) at System.Threading.Tasks.AwaitTaskContinuation.RunOrScheduleAction(IAsyncStateMachineBox box, Boolean allowInlining) at System.Threading.Tasks.Task.RunContinuations(Object continuationObject) at System.Threading.Tasks.Task`1.TrySetResult(TResult result) at System.Net.Http.ConnectHelper.EstablishSslConnectionAsync(SslClientAuthenticationOptions sslOptions, HttpRequestMessage request, Boolean async, Stream stream, CancellationToken cancellationToken) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext(Thread threadPoolThread) at System.Threading.Tasks.AwaitTaskContinuation.RunOrScheduleAction(IAsyncStateMachineBox box, Boolean allowInlining) at System.Threading.Tasks.Task.RunContinuations(Object continuationObject) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.SetExistingTaskResult(Task`1 task, TResult result) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder.SetResult() at System.Net.Security.SslStream.ForceAuthenticationAsync[TIOAdapter](TIOAdapter adapter, Boolean receiveFirst, Byte[] reAuthenticationData, Boolean isApm) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext(Thread threadPoolThread) at System.Threading.Tasks.AwaitTaskContinuation.RunOrScheduleAction(IAsyncStateMachineBox box, Boolean allowInlining) at System.Threading.Tasks.Task.RunContinuations(Object continuationObject) at System.Threading.Tasks.Task`1.TrySetResult(TResult result) at System.Net.Security.SslStream.ReceiveBlobAsync[TIOAdapter](TIOAdapter adapter) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext(Thread threadPoolThread) at System.Threading.Tasks.AwaitTaskContinuation.RunOrScheduleAction(IAsyncStateMachineBox box, Boolean allowInlining) at System.Threading.Tasks.Task.RunContinuations(Object continuationObject) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.SetExistingTaskResult(Task`1 task, TResult result) at System.Net.Security.SslStream.<FillHandshakeBufferAsync>g__InternalFillHandshakeBufferAsync|189_0[TIOAdapter](TIOAdapter adap, ValueTask`1 task, Int32 minSize) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1.AsyncStateMachineBox`1.MoveNext(Thread threadPoolThread) at System.Net.Sockets.Socket.AwaitableSocketAsyncEventArgs.InvokeContinuation(Action`1 continuation, Object state, Boolean forceAsync, Boolean requiresExecutionContextFlow) at System.Net.Sockets.Socket.AwaitableSocketAsyncEventArgs.OnCompleted(SocketAsyncEventArgs _) at System.Net.Sockets.SocketAsyncEngine.System.Threading.IThreadPoolWorkItem.Execute() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading.PortableThreadPool.WorkerThread.WorkerThreadStart() It looks like problem related to http/2 connection, but i can not find the reason anywhere.

I Have error below while testing SKAdnetwork NSAdvertisingAttributionReportEndpoint. apple docs StoreKitServiceConnection(909): Error updating install attribution conversion value: Error Domain=ASDErrorDomain Code=1208 "SKAdNetwork: No pingbacks found while attempting to register/update." UserInfo={NSLocalizedDescription=SKAdNetwork: No pingbacks found while attempting to register/update.} storekitd How can I fix it?

Hello, I have 3 questions. According to specification, it says to ignore subdomain, but if there is subdomain as follows, does it mean that SKADNetwork did not send postback? ex) test1.example.com. https://developer.apple.com/documentation/bundleresources/information_property_list/nsadvertisingattributionreportendpoint We conducted the test through the SKADNetwork test framework according to specifications, but the postback was not sent to our server. In addition, we tried to check whether SKADNetwork was working properly through advertisements directly on publisher apps and advertiser apps, but postbacks were not sent to our servers. How can I check in this case? Also, there is error log below testing with SKAdTestSession SKANTestabilitySample[14079:188474] [SKAdTestSession] Error fetching remote object proxy: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.storekit.configuration.xpc" UserInfo={NSDebugDescription=connection to service named com.apple.storekit.configuration.xpc} References: https://developer.apple.com/documentation/storekittest/testing_and_validating_ad_impression_signatures_and_postbacks_for_skadnetwork Do I have to sign a contract with Apple to get a postback of SKAD Network Attribution Report?

Hello, I Have bug while testing SKAdTestSession below error occurred when call SKAdTestSession.setPostbacks and SKAdTestSession.updatePostbackConversionValue. How can I fix it??
