I am facing the UNITYTLS_INVALID_ARGUMENT issue. Unable to resolve it.

I have added the code snippets stack trace for the issue that I am facing.

For creating client:

                client = new MqttClient(
                        brokerHostName: mqttOptions.hostname,
                        brokerPort: mqttOptions.port,
                        secure: true,
                        caCert: null,
                        clientCert: null,
                        sslProtocol: MqttSslProtocols.SSLv3);

For connection

               client.Connect(
                    clientId: GameLauncher.MqttClientData.clientId,
                    username: GameLauncher.MqttClientData.userName,
                    password: GameLauncher.MqttClientData.password,
                    willRetain: false,
                    willQosLevel: MqttMsgConnect.QOS_LEVEL_EXACTLY_ONCE,
                    willFlag: false,
                    willTopic: "",
                    willMessage: "",
                    cleanSession: mqttOptions.clean,
                    keepAlivePeriod: mqttOptions.keepalive);
