Connect exception with a connection timeout

Hi, my application is using jsmpp and needs to send an SMS via smsc located 
remotely. My machine is CentOS.
The steps are:
1. connect and authenticate with the host
2. send the sms ( According to the sample provided )
But before I can even connect, there is an exception on Timeout.
I have added the source.
Thank you for your help !
