Error sending Images/Audio using SIM7000C HTTP AT commands

Hello all,

I am trying to send Data(Images and Audio) using SIM7000C via AT commands.

The post data will be sent to a php script that will write the data to my server.

#include "SIM7000.h"
Adafruit_FONA_LTE fona = Adafruit_FONA_LTE();



char* CONTENTTYPE_IMG        =  "image/jpeg";
char* CONTENTTYPE_SOUND      =  "audio/x-wav";

boolean SIM7000_sendData(File *file, DataType_FTP_en type, String* namee)
{
  Serial.println("ENTER SEND DATA");
  int timeout = 0;
  bool error = false;
  char auxStr[150];
  uint32_t nsize = 0;
  char* script = "";
  char* content_type = "";
  String arg = "&dir=testdir&data=";
  if (type == VOICE)
  {
    *file = SD.open(WAV_FILENAME);
     nsize = file->size();
    script = SOUND_UPLOAD_SCRIPT;
    content_type = CONTENTTYPE_SOUND;
  }
  else
  {
    nsize = ESP_transferStart();
    script = IMAGE_UPLOAD_SCRIPT;
    content_type = CONTENTTYPE_IMG;
  }
  Serial.print("Sending " + String(nsize) + " bytes..");
  if (!fona.HTTP_init()) {
    Serial.println(F("httpf"));
    error = true;
    goto false_area;
  }
  Serial.println(F("HHTP OK"));
  if (!fona.sendCheckReply("AT+HTTPPARA=\"CID\",1", "OK", 10000)) {
    Serial.println(F("fail"));
    error = true;
    goto false_area;
  }
  sprintf(auxStr, "AT+HTTPPARA=\"URL\",\"%s%s\"", SERVER, script);
  if (!fona.sendCheckReply(auxStr, "OK", 10000)) {
    Serial.println(F("fail"));
    error = true;
    goto false_area;
  }

  sprintf(auxStr, "AT+HTTPPARA=\"CONTENT\",\"%s\"", content_type);
  if (!fona.sendCheckReply(auxStr, "OK", 10000)) {
    Serial.println(F("fail"));
    error = true;
    goto false_area;
  }
  SIM7000.println("AT+HTTPDATA=" + String(nsize + arg.length()) + ",120000");
  if (!fona.expectReply(F("DOWNLOAD"), 10000)) {
    Serial.println(F("DATA fail"));
    error = true;
    goto false_area;
  }

  Serial.println(F("Writing..."));
  SIM7000.print(arg);

  if (type == VOICE)
  {
      while (file->available())
      {
      SIM7000.write(file->read());
      }
      file->close();*/
  }
  else
  {
    int n = 0;
    while (nsize)
    {
      if (nsize >= ESP_CHUNK) n = ESP_CHUNK;
      else n = nsize;
      ESP_poke();
      nsize = nsize - n;
      while (n)
      {
        SIM7000.write(ESP.read());
        n--;
      }
      ESP.find("OK");
    }
    if (ESP.find("DONE")) Serial.println("IMG ok");
  }
  if (!fona.expectReply(F("OK"), 90000)) {
    Serial.println(F("DATA fail"));
    error = true;
    goto false_area;
  }
  Serial.println("Sending...");
  if (!fona.sendCheckReply("AT+HTTPACTION=1", "OK", 40000)) {
    Serial.println("Action fail");
    error = true;
    goto false_area;
  }
  timeout = 10;
  while (!SIM7000.find("+HTTPACTION: 1,200") && timeout) {
    timeout--;
    if (timeout == 0)
    {
      Serial.println("HTTPACTION fail");
      error = true;
      goto false_area;
    }
  }
  SIM7000.find("\n");

  SIM7000.println("AT+HTTPREAD");
  if (SIM7000.find("RESP="))
  {
    Serial.println(SIM7000.readStringUntil('x'));
  }
false_area:

  if (!fona.sendCheckReply("AT+HTTPTERM", "OK", 10000)) {
    Serial.println(F("fail"));
    error = true;
  }
  Serial.println("EXIT SEND DATA");
  if (!error) {
    Serial.println("Sent");
    blinkSuccess(PIN_LED_GREEN);
    return true;
  }
  blinkSuccess(PIN_LED_RED);
  return false;
}

Every command is sent correctly and it always return +HTTPACTION 1,602 (network error)

Any thoughts? Thank you.
