[emreordukaya]

Hi I try to use this api but client doesnt work.

    public async void initClient()
    {
        var settings = new FactorySettings
        {
            AppHash = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",  // e.g 456a6654ad8f52c54bc4542505884cad
            AppId = xxxxxxx, // e.g 12345
            ServerAddress = "xxx.xxx.xxx.xx",   // e.g 149.154.167.50
            ServerPublicKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",   // e.g -----BEGIN RSA PUBLIC KEY-----\nMIIBCgKCAQEAwVACPi9w23mF3tBk...
            ServerPort = xxx,  // e.g 443
            SessionTag = "Session", // by defaut
            Properties = new ApplicationProperties
            {
                AppVersion = "1.0.0", // You can leave as in the example
                DeviceModel = "PC", // You can leave as in the example
                LangCode = "en", // You can leave as in the example
                LangPack = "tdesktop", // You can leave as in the example
                SystemLangCode = "en", // You can leave as in the example
                SystemVersion = "Win 10 Pro" // You can leave as in the example
            }
        };

        // Create the client
        clientApi = await ClientFactory.BuildClientAsync(settings).ConfigureAwait(false);
        clientApi.KeepAliveConnection();

        clientApi.UpdatesService.AutoReceiveUpdates += update =>
        {
            Console.WriteLine($"updates: {JsonConvert.SerializeObject(update)}");
        };

        if (clientApi.AuthService.CurrentUserId.HasValue)
        {
            clientApi.UpdatesService.StartReceiveUpdates(TimeSpan.FromSeconds(1));
        }

        // If the user is not authenticated
        if (!clientApi.AuthService.CurrentUserId.HasValue)
        {
            // Auth
            var phone = "+90530xxxxxxx"; // User phone number with plus Turkey
            var sentCode = await clientApi.AuthService.SendCodeAsync(phone).ConfigureAwait(false);   // in this line I get System.NullReferanceExeeptions

            var code = "1234321"; // Sent code                
            try
            {
                user = await clientApi.AuthService.SignInAsync(phone, sentCode, code).ConfigureAwait(false);
            }
            // If the phone code is invalid
            catch (PhoneCodeInvalidException ex)
            {
            }
        }
        clientApi.UpdatesService.StartReceiveUpdates(TimeSpan.FromSeconds(1));
    }

System.NullReferanceExeeptions -->

I'm using the following code:

        private async Task _Connect()
        {
            Logger.Trace("Get client from client factory");
            //Create the client

            ClientApi = await ClientFactory.BuildClientAsync(Setting.GetFactorySettings()).ConfigureAwait(false);

            // If the user is not authenticated
            if (!ClientApi.AuthService.CurrentUserId.HasValue)
            {
                Logger.Trace($"Authenticate client '{Setting.PhoneNumber}' ..");
                // Auth
                var sentCode = await ClientApi.AuthService.SendCodeAsync(Setting.PhoneNumber).ConfigureAwait(false);

                TUser user;
                try
                {
                    Console.WriteLine($"Please insert authentication code '{Setting.PhoneNumber}'!",
                        "Authenticate code required");
                    var code = Console.ReadLine();

                    if (!string.IsNullOrEmpty(code))
                        user = await ClientApi.AuthService.SignInAsync(Setting.PhoneNumber, sentCode, code)
                            .ConfigureAwait(false);
                }
                // If the phone code is invalid
                catch (PhoneCodeInvalidException ex)
                {
                    Logger.Error(ex.Message);
                }
            }
        }

This works without any problems

at quick start (https://github.com/OpenTl/OpenTl.ClientApi/wiki/Quick-Start) settings variable like this;

 var settings = new FactorySettings
 {
      AppHash = // e.g 456a6654ad8f52c54bc4542505884cad
      AppId = // e.g 12345
      ServerAddress = // e.g 149.154.167.50
      ServerPublicKey = // e.g -----BEGIN RSA PUBLIC KEY-----\nMIIBCgKCAQEAwVACPi9w23mF3tBk...
      ServerPort = // e.g 443
      SessionTag = "session", // by defaut
      Properties = new ApplicationProperties
           {
                AppVersion = "1.0.0", // You can leave as in the example
                DeviceModel = "PC", // You can leave as in the example
                LangCode = "en", // You can leave as in the example
                LangPack = "tdesktop", // You can leave as in the example
                SystemLangCode = "en", // You can leave as in the example
                SystemVersion = "Win 10 Pro" // You can leave as in the example
           }
      };

and code like here but doesnt work.

// Create the client
var clientApi = await ClientFactory.BuildClientAsync(settings).ConfigureAwait(false);

You wrote as a code that;

//Create the client
ClientApi = await ClientFactory.BuildClientAsync(Setting.GetFactorySettings()).ConfigureAwait(false);

But how did you define settings variable in your code.

in addition this I sent you an email for detail ;-)

Sorry my fault, here is my TClientSetting class:

 public class TClientSetting
    {
        public string AppHash { get; set; }
        public int AppId { get; set; }
        public string ServerAddress { get; set; }
        public string ServerPublicKey { get; set; }
        public int ServerPort { get; set; }
        public string PhoneNumber { get; set; }
        public string PhoneNumberSentCode { get; set; }
        public string SessionTag { get; set; }

        public List<ObservedEntity> ObservedEntities { get; set; } = new List<ObservedEntity>();

        public FactorySettings GetFactorySettings()
        {
            var settings = new FactorySettings
            {
                AppHash = AppHash,
                AppId = AppId,
                ServerAddress = ServerAddress,
                ServerPublicKey = ServerPublicKey,
                ServerPort = ServerPort,
                SessionTag = $"TSession_{PhoneNumber}", // by defaut
                Properties = new ApplicationProperties
                {
                    AppVersion = Assembly.GetExecutingAssembly().GetName().Version.ToString(), // You can leave as in the example
                    DeviceModel = "PC", // You can leave as in the example
                    LangCode = "de", // You can leave as in the example
                    LangPack = "tdesktop", // You can leave as in the example
                    SystemLangCode = "de", // You can leave as in the example
                    SystemVersion = "Win 10 Pro" // You can leave as in the example
                }
            };
            return settings;
        }
    }

[alessandrobernardin]

you have to use the certificate with "returns"
ServerPublicKey ="-----BEGIN RSA PUBLIC KEY-----\n" +
"MIIBCgKCAQEAwVACPi9w23mF3tBkdZz+zwrzKOaaQdr01vAbU4E1pvkfj4sqDsm6\n" +
"lyDONS789sVoD/xCS9Y0hkkC3gtL1tSfTlgCMOOul9lcixlEKzwKENj1Yz/s7daS\n" +
...
"-----END RSA PUBLIC KEY-----"

and work fine
