QUrl can't parse some web urls

Harry56

    QString url = "https://lichess.org/Mq8MR9ri";
    QNetworkAccessManager manager;
    QNetworkReply* response = manager.get(QNetworkRequest(QUrl(url)));
    QEventLoop event;
    QObject::connect(response, SIGNAL(finished()), &event, SLOT(quit()));
    event.exec();
    QString content = response->readAll();
    qInfo() << content;

this is my code, it works fine for some link, but for some links, not.
for example : QString url = "https://lichess.org/vAArADOV3ege";
response->url().host(); returns wrong path...

Hello and welcome.

Purely a guess. When I paste your first working URL, https://lichess.org/Mq8MR9ri, into Chrome it takes me to that exact URL. But when I paste your second non-working URL, https://lichess.org/vAArADOV3ege, it seems to redirect me to https://lichess.org/vAArADOV/black. Is this significant?

@Harry56 add manager.setRedirectPolicy(QNetworkRequest::SameOriginRedirectPolicy); after QNetworkAccessManager manager;

QNetworkReply* response = manager.get(QNetworkRequest(QUrl(url)));
QEventLoop event;
QObject::connect(response, SIGNAL(finished()), &event, SLOT(quit()));
event.exec();

qInfo() << response->errorString();

"Host not found."

Yes, https://lichess.org/vAArADOV/black works, but why does redirect not works?

Thanks for answering
