com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

Hi,
Sorry for my Ebglish.
I have a strange problem, getting com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
in a netbeans desktop application that has a connection to a remote server . MySql database located in the server.
I am getting the connection once:
con = DriverManager.getConnection(connectionUrlInternet);
Then I am creating statements on this connection to update/insert data.
My system worked just fine for 1.5 years , once a week I had those
Communications link failure if at all.
Lately I am getting the failure every few minutes, the meanning - we cannot work.
The remote server manager cannot solve the problem - he didn't change anything.
He wants me to get the connection before each operation and close it.

Any idea please, I am lost.

Thank you
Miriam
