[SOLVED] Ethernet_STM Library client.read() dont work

// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
IPAddress gateway( 192, 168, 10, 3);
IPAddress subnet( 255, 255, 255, 0 );
IPAddress dns1( 59, 144, 127, 16);
//IPAddress server(192, 168, 10, 191);
IPAddress ip(192, 168, 10, 11);
char server[] = "https://test-turnstile.gymshim.com";
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;

void setup() {

Serial.begin(9600); // init Serial USB
while (!Serial); delay(10);
Serial.println("Hello from USB Serial !!");
Ethernet.begin(mac, ip, dns1, gateway, subnet);

void loop() {
// check for serial input
if (Serial.available() > 0) //if something in serial buffer

inChar = Serial.read(); //gets byte from buffer
if (inChar == 'e') // checks to see byte is an e
{
sendGET();
}
}
}

void sendGET()
{
if (client.connect(server, 80)) { //starts client connection, checks for connection
Serial.println("connected");

This sketch connects to a website (http://www.google.com)
using an Arduino Wiznet Ethernet shield.
