Problem sending files via : +FTPPUT: 1,77

Hi, everybody im having an issue with my code when im trying to send a file from an SD to a FTP Server.

It always responds with +FTPPUT: 1,77, does anybody have the same issue and find a solution ?

I share the code:

#include <SoftwareSerial.h>
#include <SD.h>
#include <SPI.h>
#include “eMGing_900_808.h”

#define EMGING_TX 10
#define EMGING_RX 8
#define SD_PIN 9

//SoftwareSerial eMGing(8, 10); // Pin RX(8) y TX(10)
SoftwareSerial eMGingSS = SoftwareSerial(EMGING_TX, EMGING_RX);
SoftwareSerial *eMGingSerial = &eMGingSS;

eMGing_900_808 eMGing = eMGing_900_808(4);

const char* file_to_send = “test1.txt”;
String ruta_carpeta = “/ id5367 /”;

char char_buffer;
String string_buffer = “”;
int buffer_space = 100;
File File1;

void setup()
{
Serial.begin(eMGingSSBaud);
if (!SD.begin(SD_PIN)) {
Serial.println(“inicializacion SD NO!”);
return;
while(true);
}else {
Serial.println(“inicializacion SD OK.”);
}

audio.CSPin = SD_PIN;
eMGingSerial->begin(19200);

if (! eMGing.begin(*eMGingSerial)) {
Serial.println(F(“No se encontro el shield”));
while (1);
}
Serial.println(F(“El Shield eMGing esta OK”));
void loop()
{

while ( eMGing.available() > 0) eMGing.read(); // Limpia el buffer de entrada

x = 0;

// Espera una respuesta
do {
// si hay datos el buffer de entrada del UART lee y comprueba la respuesta
if (eMGing.available() != 0)
{
respuesta = eMGing.read();
x++;
// Comprueba si la respuesta es correcta
if (strstr(respuesta, resp_correcta) != NULL)
{

}
}
}
// Espera hasta tener una respuesta
while ((correcto == 0) && ((millis() - anterior) < tiempo));
Serial.println(respuesta);
}

If someone can help me with this i would so gratful.

Thanks.
