Qt Remote Database connection

112.17.98.18 is this in LAN ? Hope there is no firewall etc between your box and 112.17.98.18.
Since telnet is not able to connect to port 111 are you sure that SQL is running at the port 111 ?@dheerendra
Sir SQL is not running in the port 111.Sql port is 3306 .. -
OK can you check telnet 112.17.98.18 3306 ? Does it work ? If it work, atleast DB is up at that port.

@dheerendra sir it shows telnet: Unable to connect to remote host: Connection refused

If you have access to the DB Server box, can you login to the system. In same system can you try to do telnet <IP> Port#. Just check the configuration of the remote sql server. Is it configured to listen for network connections also ?

@dheerendra bind address commented. it was 127.0.0.1 (/etc/mysql/mysql.cnf);

Your server was configured to listen only for local IP address. You tried to connect to server remotely. This was the issue.

It's Qt not QtCreator. QtCreator is an IDE.
See https://doc.qt.io/qt-5.11/qtnetwork-programming.html -
Mysql or mariadb listen by default to the loopback address 127.0.0.1
you can change this values to the real local networkaddress in
/etc/mysql/ mysqld.cnfbind-address = 192.178.xx.xx
mysqlx-bind-address = 192.178.xx.xxrestart the sql.
that's it
