Can't connect to MySQL server on '192.xxx.x.x' (111) QMYSQL: Unable to connect

[shawshank]

I am trying to sync two databases using a local IP. Though I have the QMYSQL driver installed properly it still gives an error for connection failed.
A main database is created on host computer and I'm trying to sync data from another computer to this database through a local network.
Code on host computer:

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL","Host");
    db.setHostName("HOSTIP");
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("toor");

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL","Host");
    db.setHostName("HOSTIP");
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("toor");

To copy to clipboard, switch view to plain text mode 

Code on other computer:

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL","Other");
    db.setHostName("IP OF HOST");
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("toor");

QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL","Other");
    db.setHostName("IP OF HOST");
    db.setDatabaseName("test");
    db.setUserName("root");
    db.setPassword("toor");

Any help is appreciated!!
