Hi everybody, this is my first post, so I hope I'm doing the right moves on the forum !  
I'm quite new about Arduino and I'm working on a "classic" project, but with a issues that I didn't solve.  
I use a Arduino Uno WIFI Rev 2 to connect to a wifi and send data by using POST request to a webserver. I used WifiNINA and ArduinoJSON.  
The problem is: I never entered inside the IF after client.connectSSL, because by using a browser I need to login with username and password in a classic login page...but I don't find working solutions with Arduino.  
The code that I'm using is the following:

```cpp
#include <WiFiNINA.h>
#include <ArduinoJson.h>
#include <SPI.h>

char ssid[] = "XXXXXXXXXXXXXXXXXX";
char pass[] = "XXXXXXXXXXXXXXXXXX";

int status = WL_IDLE_STATUS;
DynamicJsonDocument doc(1024); // 
char server[] = "https://XXXXXXXXXXXXX";

WiFiClient client;

void setup() {

  Serial.begin(9600);

  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to Network named: ");
    Serial.println(ssid);
    status = WiFi.begin(ssid, pass);
    delay(5000);
  }

  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());
  IPAddress ip = WiFi.localIP();
  IPAddress gateway = WiFi.gatewayIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  String fv = WiFi.firmwareVersion();
  if (fv != "1.4.8") {Serial.println("Please upgrade the firmware"); }
} // end setup

void loop() {
  
 
  doc["XXXXX"][0] = "XXXXXX";
  doc["XXXX"] = "XXXXX";
  doc["XXXXX"] = "XXXXXX";
  
  Serial.print("Provo a connettermi !...\n\r ");
  if (client.connectSSL(server, 443)) {
	
    Serial.print("Sono connesso !...invio la richiesta POST \n\r ");
    client.println("POST \'https://XXXXXXXXX' ");
   // client.println("Host: https://XXXXXXXX");
    client.println("accept: application/ld+json"); 
    client.println("Content-Type: application/ld+json"); 
    client.println("Connection: close");  
    client.print("Content-Length: 1024");
    client.println(measureJson(doc)); 
    client.println();
    serializeJson(doc, client);
  // client.print(doc);
  }
  else{Serial.print("Non sono connesso \n\r");}

  if (client.connected()) {
    client.stop();
  }
   Serial.print("Risultato...: ");
  Serial.println(serializeJson(doc, client));

  delay(3000);
}

```

Thank you !

I think you will need to remove the "1024".

You may need to send the data to the client before you stop it.

Thank you very much johnwasser and I agree, but the main problem is that I don't reach the server under https !  
I've tried even with ArduinoHttpClient library, but the best case is to receive a 400 error or a timeout !
