[Arduino Uno WiFi rev2] Cant connect to localhost

Using the example from Examples -> WiFiNINA -> ConnectWithWPA on my Arduino Uno rev2.

I can connect to Google either with www.GOOGLE.com or the Google IP 74.125.224.212
I can connect to my Azure function app endpoints on the internet

I can connect with my localhost endpoint using Chrome with the url http://localhost:7071/api/FindPlayersByCountry?country=Taiwan&season=2020.

I can connect with my localhost endpoint using Chrome with the url http://192.168.1.14:7071/api/FindPlayersByCountry?country=Taiwan&season=2020.

I can also connect with my localhost endpoint using Chrome on another computer (RaspberryPi) within the same WiFi network by hitting the same url http://192.168.1.14:7071/api/FindPlayersByCountry?country=Taiwan&season=2020.

But I can't seem to connect to the local endpoint from my Arduino using the following code... When I run the code below all I see is

Starting connection to server...


disconnecting from server.

Can anyone shad some light for me please?

Notes: the firewall on my MAC is turned off, if this help.

Thanks!!

#include <SPI.h>
#include <WiFiNINA.h>
#define SECRET_SSID "MY_SSID"
#define SECRET_PASS "MY_PASSWORD"

///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID;        // your network SSID (name)
char pass[] = SECRET_PASS;    // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0;            // your network key Index number (needed only for WEP)

int status = WL_IDLE_STATUS;
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
IPAddress server(192, 168, 1, 14);  // numeric IP for Google (no DNS)

// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
WiFiSSLClient client;

void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // check for the WiFi module:
  if (WiFi.status() == WL_NO_MODULE) {
    Serial.println("Communication with WiFi module failed!");
    // don't continue
    while (true);
  }

  String fv = WiFi.firmwareVersion();
  if (fv < WIFI_FIRMWARE_LATEST_VERSION) {
    Serial.println("Please upgrade the firmware");
  }

  // attempt to connect to WiFi network:
  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
    status = WiFi.begin(ssid, pass);

    // wait 10 seconds for connection:
    delay(10000);
  }
  Serial.println("Connected to wifi");
  printWiFiStatus();

  Serial.println("\nStarting connection to server...");
  // if you get a connection, report back via serial:
  if (client.connect(server, 7071)) {
    Serial.println("connected to server");
    // Make a HTTP request:
    client.println("GET /api/FindPlayersByCountry?country=Taiwan&season=2020 HTTP/1.1");
    client.print("Host: ");
    client.println(server);
    client.println("Connection: close");
    client.println();
  }
}

void loop() {
  // if there are incoming bytes available
  // from the server, read them and print them:
  while (client.available()) {
    char c = client.read();
    Serial.write(c);
  }

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting from server.");
    client.stop();

    // do nothing forevermore:
    while (true);
  }
}

Problem solved. For anyone who wants to hit a local endpint/url from their Arduino, use Examples -> WiFiNINA -> WiFiWebClient
