Seems that the lib is not not responding to the board or am i making anzthing wrong

Hello @JacobEPTechnologies421,

Thank you for reaching out. I was able to run the modified version of the code you provided and it worked as expected on an Arduino Uno R4 WiFi Board. Make sure your WiFi is working properly, and your Arduino board and libraries are up to date.

hi, the issue still persits, with zour code I get a return value as 0

Hello,

I'm unable to replicate the issue on my end, and it's unclear where the system might be failing. It could be something as simple as a VPN or firewall issue. To start with the basics, could you please upload the following code and share the output?

#include "WiFiS3.h"
#include "WiFiSSLClient.h"

char ssid[] = "your_SSID";        // Your network SSID (name)
char pass[] = "your_PASSWORD";    // Your network password

WiFiSSLClient client;
char server[] = "www.google.com";  // Server to connect to

void setup() {
  Serial.begin(115200);
  while (!Serial) { ; }  // Wait for serial port to connect

  // Check if the Wi-Fi module is present
  if (WiFi.status() == WL_NO_MODULE) {
    Serial.println("WiFi module not found!");
    while (true);
  }

  // Check firmware version
  String fv = WiFi.firmwareVersion();
  if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
    Serial.println("Please update the WiFi firmware!");
  }

  // Connect to Wi-Fi network
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print("Connecting to SSID: ");
    Serial.println(ssid);
    WiFi.begin(ssid, pass);
    delay(10000);  // Wait 10 seconds for connection
  }

  Serial.println("WiFi connected");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());

  // Connect to the server
  if (client.connect(server, 443)) {
    Serial.println("Connected to server");

    // Send HTTP GET request
    client.println("GET / HTTP/1.1");
    client.println("Host: www.google.com");
    client.println("Connection: close");
    client.println();
  } else {
    Serial.println("Connection to server failed");
  }
}

void loop() {
  // Read and print server response
  while (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  // Disconnect from the server
  if (!client.connected()) {
    Serial.println();
    Serial.println("Disconnecting...");
    client.stop();
    while (true);
  }
}
