You must pass it the complete route, that is:

nombre_del_bloque/palabra_clave

In your case:

qsettings=new QSettings(QString(":/config/config.ini"), QSettings::IniFormat);
QString database = qsettings->value("DBDefault/db", "").toString();
QString server=qsettings->value("DBDefault/server","").toString();
QString port=qsettings->value("DBDefault/port","").toString();

qDebug()<<database<<server<<port;

Exit:

"dgt" "193.147.83.170" "5432"

Recommendation: For future publications it is better to place the necessary code.

This already works

 QString configFile = QCoreApplication::applicationDirPath() +"/config/config.ini";
    QSettings qsettings(configFile,QSettings::IniFormat);

    qsettings.beginGroup("DBDefault");
    QString database=qsettings.value("db","").toString();
    QString server=qsettings.value("server","").toString();
    QString port=qsettings.value("port","").toString();
    qsettings.endGroup();
