Yet another guy with a 400 error.

So, I recently got a Mega set up with the ethernet shield, and I'm trying to get the very simple index.html from a site (http://bulbrelay.000webhostapp.com/). Here is the code I am using:

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

//IPAddress server(74,125,232,128);  // numeric IP for Google (no DNS)
char server[] = "bulbrelay.000webhostapp.com";    // name address (using DNS)

// Set the static IP address to use if the DHCP fails to assign
IPAddress ip(192, 168, 0, 177);
IPAddress myDns(192, 168, 0, 1);

// 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() {
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }
  // start the Ethernet connection:
  Serial.println("Initialize Ethernet with DHCP:");
  Ethernet.begin(mac);
  Serial.print("  DHCP assigned IP ");
  Serial.println(Ethernet.localIP());
  // give the Ethernet shield a second to initialize:
  delay(1000);
  Serial.print("connecting to ");
  Serial.print(server);
  Serial.println("...");

  // if you get a connection, report back via serial:
  if (client.connect(server, 80)) {
    Serial.print("connected to ");
    Serial.println(client.remoteIP());
    // Make a HTTP request:
    client.println("GET http://bulbrelay.000webhostapp.com/ HTTP/1.1");
    client.println();
  } else {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
  }
}

void loop() {
  // if there are incoming bytes available
  // from the server, read them and print them:
  int len = client.available();
  if (len > 0) {
    byte buffer[80];
    if (len > 80) len = 80;
    client.read(buffer, len);
      Serial.write(buffer, len); // show in the serial monitor (slows some boards)

  }

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    // do nothing forevermore:
    while (true) {
      delay(1);
    }
  }
}

And I get the standard 400 bad request return from the console. With other sites, such as server[] = go.com and the get as http://go.com/ HTTP/1.1, it works fine! Just not for my site (which has a filler of just one string of text right now).

Thank you guys for taking the time to look over this!

client.println("GET http://bulbrelay.000webhostapp.com/ HTTP/1.1") ;

Try removing http://

3

Try this: client.println("GET / HTTP/1.1") ;

4 
   client.println("GET / HTTP/1.1");
   client.println("Host: bulbrelay.000webhostapp.com");
   client.println();

I'd tried just with the / and removing http://, but

   client.println("GET / HTTP/1.1");
   client.println("Host: bulbrelay.000webhostapp.com");
   client.println();

did the trick! Thank you guys!

it is a hosting server. without the host name "bulbrelay" it doesn't know which application is requested
