Arduino的以太网盾没有连接到Web服务器(Arduino Ethernet Shield No

我已经让我的Arduino的以太网盾与服务器进行通信的问题，串行监视器上的结果总是：

我的Arduino代码

#include <Ethernet.h>           //library for ethernet functions
#include <SPI.h>
#include <Dns.h>
#include <Client.h>             //library for client functions
#include <DallasTemperature.h>  //library for temperature sensors

// Ethernet settings
byte mac[] = {0x09,0xA2,0xDA,0x00,0x01,0x26};  //Replace with your Ethernet shield MAC
byte ip[] = { 192,168,0,54};  //The Arduino device IP address
byte subnet[] = { 255,255,255,0};
byte gateway[] = { 192,168,0,1};
IPAddress server(192,168,0,53);                  // IP-adress of server arduino sends data to

EthernetClient client;

bool connected = false;                                

void setup(void) {                                     

    Serial.begin(9600);                                
    Serial.println("Initializing Ethernet.");
    delay(1000);
    Ethernet.begin(mac, ip , gateway , subnet);    

}

void loop(void) {                                      

    if(!connected)   {                                 
      Serial.println("Not connected");
      if (client.connect(server, 80)) {                
          connected = true;
          int temp =analogRead(A1);                    
          Serial.print("Temp is ");                              
          Serial.println(temp);
          Serial.println();
          Serial.println("Sending to Server: ");                 
          client.print("GET /formSubmit.php?t0=");            
          Serial.print("GET /formSubmit.php?t0=");            
          client.print(temp);
          Serial.print(temp);
          client.println(" HTTP/1.1");                  
          Serial.println(" HTTP/1.1");                  
          client.println("Host: http://localhost/PhpProject1/");    
          Serial.println("Host: http://localhost/PhpProject1/");    
          client.println("User-Agent: Arduino");        
          Serial.println("User-Agent: Arduino");        
          client.println("Accept: text/html");          
          Serial.println("Accept: text/html");          
          //client.println("Connection: close");        
          //Serial.println("Connection: close");        
          client.println();                             
          Serial.println();
          delay(10000);                                            
      }
      else{
        Serial.println("Cannot connect to Server");               
      }
    }  
    else {
      delay(1000);                                              
      while (client.connected() && client.available()) {        
        char c = client.read();                                 
        Serial.print(c);                                        
      }                                                         
      Serial.println();                                         
      client.stop();                                            
      connected = false;                                        
    }
}

服务器是一台PC上运行的Apache服务器，在代码服务器IP地址是PC端IP地址。出于测试目的，我在我的家庭网络工作，有没有代理服务器或防火墙，我也变成了杀毒软件和防火墙在我的电脑中。

结果在串行监控始终是：
