QNetworkAccessManager doesn't call QNetworkReply

So i made a program that connects to Youtube, downloads the page and parses for video title and tags. It works fine for 5-6 times the request is being called, but then the functionality of the youtube class stops, and processor usage rises to 12% and stays at this level. This is my code

Code:

---

#include "youtube.h"
#include <QByteArray>
#include <QNetworkCookieJar>
#include "youtube.h"
 
Youtube::Youtube(QObject *parent)
{
    manager = new QNetworkAccessManager(this);
    manager->setCookieJar(this);
    connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(slotReadyRead(QNetworkReply*)));
 
    auto aName = manager->objectName();
    connect(manager, &QNetworkAccessManager::encrypted,
               this, [aName]{  qDebug()<< "connect - encrypted";  });
}
 
void Youtube::makeRequest(QString indexCore)
{
    youtubeActive_is = true;
    url =  "https://" +  indexCore;
    QUrl urlForCookies (url);
 
    request.setRawHeader("COOKIE" , "CONSENT=YES+42"); //works
    request.setUrl(urlForCookies);
    manager->get(request);
}
 
 
void Youtube::slotReadyRead(QNetworkReply *replay)
{
    QByteArray dataTemp = replay->readAll();
    website = dataTemp.toStdString();
 
        if(website.size()!=0)
        {
            Parser parser;
            std::string title = parser.extract_tagContent(website, "title");
 
            title = "\u00034" +title;
            postToIRC(title);
 
            youtubeActive_is = false;
        }
 
 
        manager->autoDeleteReplies(); 
        manager->clearAccessCache();
        manager->clearConnectionCache();
 
        replay->abort();
        replay->close();
        replay->deleteLater();
 
        for (int i = 0; i < allCookies().size(); ++i) {
            manager->cookieJar()->deleteCookie(allCookies().at(i));
        }
    }
