ethercard : unable to send httppost request

I am writing a code to send my arduino ip to my server but i am not getting any request from arduino even after sending request i don’t know what is wrong with my code.The line ether.tcpsend() is executed in the code but i am not recieving any request.

#include <EtherCard.h>

#define STATIC 0  // set to 1 to disable DHCP (adjust myip/gwip values below)

// mac address
static byte mymac[] = { 0x74, 0x69, 0x69, 0x2D, 0x30, 0x31 };
// ethernet interface ip address
static byte myip[] = { 172, 26, 40, 250 };
// gateway ip address
static byte gwip[] = { 172, 26, 40, 1 };

// LED to control output
int fPin = 10;
int bPin = 9;

byte Ethernet::buffer[700];

const char website[] PROGMEM = "172.26.42.240";
Stash stash;


void sendData() {   // function to send post request 


Stash stash;

byte sd = stash.create();

 stash.print("ip=");
 stash.print("ip");
 stash.print("&mac=");
 stash.println("mac");
 stash.save();
 
 int stash_size = stash.size();

 Stash::prepare(PSTR("POST http://$F:8080/Connect/Arduino_data HTTP/1.0" "\r\n"
    "Host: $F:8080" "\r\n"
    "Content-Length: $D" "\r\n"
    "\r\n"
    "$H"),
ether.hisip, ether.hisip, stash_size, sd);   // i tried placing website in place of ether.hisip but it is not working either

ether.tcpSend();

}

void setup () {
  pinMode(fPin, OUTPUT);
  pinMode(bPin, OUTPUT);

  digitalWrite(bPin,HIGH);

  Serial.begin(9600);
  Serial.println("Trying to get an IP...");

  Serial.print("MAC: ");
  for (byte i = 0; i < 6; ++i) {
    Serial.print(mymac[i], HEX);
    if (i < 5)
      Serial.print(':');
  }

  ether.begin(sizeof Ethernet::buffer, mymac, 8);


#if STATIC
  Serial.println( "Getting static IP.");
  if (!ether.staticSetup(myip, gwip)) {
    Serial.println( "could not get a static IP");

  }
#else

  Serial.println("Setting up DHCP");
  if (!ether.dhcpSetup()) {
    Serial.println( "DHCP failed");

  }
#endif

  ether.printIp("My IP: ", ether.myip);
  ether.printIp("GW IP: ", ether.gwip);
  ether.printIp("DNS IP: ", ether.dnsip);


  ether.hisip[0] = 172;
  ether.hisip[1] = 26;
  ether.hisip[2] = 42;
  ether.hisip[3] = 240;
  ether.hisport = 8080;

  sendData();     // function call to send post request

}

void loop () {

  word len = ether.packetReceive();
  word pos = ether.packetLoop(len);

  if (strstr((char *)Ethernet::buffer + pos, "GET /?PIN9=ON") != 0) {
    Serial.println("Received ON command");
    digitalWrite(bPin, HIGH);
  }

  if (strstr((char *)Ethernet::buffer + pos, "GET /?PIN9=OFF") != 0) {
    Serial.println("Received OFF command");
    digitalWrite(bPin, LOW);
  }

  if (strstr((char *)Ethernet::buffer + pos, "GET /?PIN10=ON") != 0) {
    Serial.println("Received ON command");
    digitalWrite(fPin, HIGH);
  }

  if (strstr((char *)Ethernet::buffer + pos, "GET /?PIN10=OFF") != 0) {
    Serial.println("Received OFF command");
    digitalWrite(fPin, LOW);
  }
  
}

ether.tcpsend() returns 1

Hi, I am experiencing the same problem.

I tryied many ways and with the same result.

Could someone help us ?
