Uno WiFi Rev2 “no socket available”

Hey guys, I know that this problem is not new, but the usual fix with using client.flush() and client.stop() isn't working for me. I use the newest firmware and library.

So this is the important part of my code. It's a bit messy, sorry for that.

#include <SPI.h>
#include <WiFiNINA.h>

//W-Lan Data
int status = WL_IDLE_STATUS;
char ssid[] = "**********";
char pass[] = "**********";

bool jsonBool;
char jsonChar;
int curlyBracket;
String jsonCode;
String json;

IPAddress HueBridge(10, 0, 0, 30);

WiFiClient WHTTP;

void setup() {
  while (status != WL_CONNECTED) {
    status = WiFi.begin(ssid, pass);
    delay(500);
  }
}

void loop() {
  jsonProcessing();
  httpRequest();

  bar1();

  delay(55);
}

void httpRequest() {
  WHTTP.flush();
  WHTTP.stop();
  if(WHTTP.connect(HueBridge, 80)) {
    WHTTP.println("GET /api/*************/lights/ HTTP/1.1");
    WHTTP.println("Host: 10.0.0.30");
    WHTTP.println("Connection: close");
    WHTTP.println();
  }
}

void jsonProcessing() {
  while(WHTTP.connected()) {
    if(WHTTP.available()) {
      curlyBracket = 7;
      while(WHTTP.available()) {
        jsonChar = WHTTP.read();
        if((jsonChar == '{') && (curlyBracket == 7)) {
          jsonBool = true;
          curlyBracket = 0;
        }
        if(jsonChar == '}') {
          jsonBool = false;
          jsonCode = jsonCode + '}';
          curlyBracket++;
        }
        if(jsonBool) {
          jsonCode = jsonCode + jsonChar;
        }
      }
    }
    WHTTP.flush();
    WHTTP.stop();
  }
  jsonBool = false;

  //processing jsonCode variable

  jsonCode = "";
}

void bar1() {
  //calculating stuff
}

If anything is unclear feel free to ask me.

There is also a thread on stackexchange about this, with no answer yet. (Arduino Uno WiFi Rev2 "no socket available" - Arduino Stack Exchange)

So thank you in advance!
