connect error 203

[lipun4u]

I am trying to fetch something from internet.

Here is the sample code

private slots:
    void replyFinished(QNetworkReply *reply);
    void replyError(QNetworkReply::NetworkError code);
public:
    QTwitterClient(QObject *parent=0);
    void Fetch(const QString& url);
 
public slots:
    void print(QString response);
signals:
    void finished(QString url);
    void failed(QString errorString);
};
#endif // TWIT_H

#include <QObject>

public slots:
    void print(QString response);
signals:
    void finished(QString url);
    void failed(QString errorString);
};

When I build and run this, this is giving me some kind of connect() error

Starting /home/asit/qt/twit1-build-desktop/twit1...
Error code: 203 
"Network result code: 203"

Starting /home/asit/qt/twit1-build-desktop/twit1...
Error code: 203 
"Network result code: 203"

Can anyone tell me how to fix this ?

The error is, QNetworkReply::ContentNotFoundError(203)-the remote content was not found at the server (similar to HTTP error 404)

Here is the Link

Check the Url and make sure the server is reachable. Is the Url reachable using a browser?
