I get the following response from the console:

For this I've used the following sample code:
#include <MKRGSM.h>
#include "arduino_secrets.h"
const char PINNUMBER[] = SECRET_PINNUMBER;
// APN data
const char GPRS_APN[] = SECRET_GPRS_APN;
const char GPRS_LOGIN[] = SECRET_GPRS_LOGIN;
const char GPRS_PASSWORD[] = SECRET_GPRS_PASSWORD;
// initialize the library instance
GSMClient client;
GPRS gprs;
GSM gsmAccess(true);
// URL, path and port (for example: example.org)
char server[] = "ifconfig.me";
char path[] = "/ip";
int port = 80; // port 80 is the default for HTTP
void setup() {
// initialize serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Starting Arduino web client.");
// connection state
bool connected = false;
// After starting the modem with GSM.begin()
// attach the shield to the GPRS network with the APN, login and password
while (!connected) {
if ((gsmAccess.begin(PINNUMBER) == GSM_READY) &&
(gprs.attachGPRS(GPRS_APN, GPRS_LOGIN, GPRS_PASSWORD) == GPRS_READY)) {
connected = true;
} else {
Serial.println("Not connected");
delay(1000);
}
}
Serial.println("connecting...");
// if you get a connection, report back via serial:
if (client.connect(server, port)) {
Serial.println("connected");
// Make a HTTP request:
client.print("GET ");
client.print(path);
client.println(" HTTP/1.1");
client.print("Host: ");
client.println(server);
client.println("Connection: close");
client.println();
} else {
// if you didn't get a connection to the server:
Serial.println("connection failed");
}
}
void loop() {
// if there are incoming bytes available
// from the server, read them and print them:
if (client.available()) {
char c = client.read();
Serial.print(c);
}
// if the server's disconnected, stop the client:
if (!client.available() && !client.connected()) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
}
}
It once worked pretty good but for some time now it doesn't what can I do? Maybe use a different antenna?
