What investigation have you already done to isolate the problem ?
Is it clear to you if the problem is on the HTML side or the Web Server side ?
What happens if you issue this command in a web browser in the same network as the web server:
Does the Led light ?
Do you see the text “Serial check!” in the serial console of the Arduino ?
Why do you have two serial ports? Are you not using an Arduino UNO?:
Serial.println("Initializing SD card..."); // c√†i ƒë·∫∑t th·∫ª SD
d = Nhan.read_uint8_t();
