Are you sure that the mess you are sending is correct? Generally, commands are separated by carriage returns AND line feeds.

There is no need to crap the code up using Strings.

Serial.println("GET /arduino.php?registro=RPA&n=Temperatura&v=14 HTTP/1.1");
  nss.println("GET /arduino.php?registro=RPA&n=Temperatura&v=14 HTTP/1.1");
Serial.println("Host: 200.27.90.43");
  nss.println("Host: 200.27.90.43");
Serial.println("Connection: close");
  nss.println("Connection: close");
Serial.println();
 nss.println();

Will do nearly the same thing, without pissing away resources using the String class.
