Describe the problem

Making a page request to www.arduino.cc results in a 403 error.

To reproduce

  1. Mount the MKR ETH Shield onto the MKR WiFi 1010
  2. Connect an ethernet cable from the MKR ETH Shield to a router. Similar to image below
    image
  3. Compile and upload the WebClientRepeating.ino sketch without any modifications. While uploading, use a thin plastic stylus to reset the board.
  4. Upon establishing a connection, a message similar to the following is continuously displayed.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Expected behavior

According to the line below, the sketch should connect to the arduino.cc website.

Ethernet/examples/WebClientRepeating/WebClientRepeating.ino

Line 40 in d31148d

char server[] = "www.arduino.cc"; // also change the Host line in httpRequest()

Ethernet/examples/WebClientRepeating/WebClientRepeating.ino

Lines 104 to 126 in d31148d

// this method makes a HTTP connection to the server:
void httpRequest() {
// close any connection before send a new request.
// This will free the socket on the Ethernet shield
client.stop();
// if there's a successful connection:
if (client.connect(server, 80)) {
Serial.println("connecting...");
// send the HTTP GET request:
client.println("GET /latest.txt HTTP/1.1");
client.println("Host: www.arduino.cc");
client.println("User-Agent: arduino-ethernet");
client.println("Connection: close");
client.println();
// note the time that the connection was made:
lastConnectionTime = millis();
} else {
// if you couldn't make a connection:
Serial.println("connection failed");
}
}

However, it does not get the full HTML website. But rather a Cloudfire error message.

When replacing www.arduino.cc with www.google.com a 404 error (instead of the 403 error) occurs.
