I trying to do a request to apns server with http2 request but i got this error message :

Only HTTP/1.0 and HTTP/1.1 version requests are currently supported.\r\nParameter name: value

My request :

public static async Task<string> SendManualApns(int type, long? requestId, string title, string message, int badge, string deviceToken)
{
    var cert = new X509Certificate2(HttpContext.Current.Server.MapPath(ApnCertPath), ApnCertPassword, X509KeyStorageFlags.MachineKeySet);
    var req = new HttpRequestMessage(HttpMethod.Post, "https://api.sandbox.push.apple.com/3/device/" + deviceToken);
    req.Version = new Version(2, 0);
    req.Headers.Add("apns-topic", cert.Subject.Substring(cert.Subject.LastIndexOf('=') + 1));

    string sound = type == (short)NotificationType.RequestTechnicianNow ? "spaceBell.caf" : "default";
    string category = type == (short)NotificationType.RequestTechnicianNow ? "nowRequestCategory" : "none";
    req.Content = new StringContent("{\"aps\":{\"alert\":{\"title\":\"" + title + "\",\"body\":\"" + message + "\"},\"badge\":" + badge + ",\"sound\":\"" + sound + "\",\"requestId\":" + requestId + ",\"type\":" + type + ",\"category\":\"" + category + "\"}}");
    var handler = new HttpClientHandler { ClientCertificateOptions = ClientCertificateOption.Manual };
    handler.ClientCertificates.Add(cert);
    var response = await new HttpClient(handler).SendAsync(req);
    string content = await response.Content.ReadAsStringAsync();
    if (!response.IsSuccessStatusCode)
        return "APNS error " + response.StatusCode + ": " + content;

    return "success";
}

I using .netframework 4.7.2 in asp.net mvc webapi 2 project

I was using pushsharp but it stopped because it is not support http2 yet

By default HttpClient uses HTTP 1.1 as mentioned in ms doc

you can try, following way to explicitly tell client object to use version 2

var client = new HttpClient()
{
    BaseAddress = new Uri("https://localhost:5001"),
    DefaultRequestVersion = new Version(2, 0)
};

Alternatively, you can use Nuget Package WinHttpHandler and pass this handler to client object like,

var handler = new WinHttpHandler();
var client = new HttpClient(handler);

You can check the discussion around this here

If using asp.net webform then install below package first

WinHttpHandler Nuget Package

and use the below code

var apnSettings = new ApnSettings
{
AppBundleIdentifier = "",
P8PrivateKey = "",
P8PrivateKeyId = "",
TeamId = "",
ServerType = ApnServerType.Development
};

var httpHandler = new WinHttpHandler();
var httpClient = new HttpClient(httpHandler);
var apn = new ApnSender(apnSettings, httpClient);
var payload = new AppleNotification(Guid.NewGuid(), messageBody, "MyNotification");
var apnsResponse = Task.Run(() => apn.SendAsync(payload, deviceId)).Result;
