Use ConnectionTimeout to specify the amount of time, in seconds, that can expire before an attempt to make a connection is considered unsuccessful. The default value is 15 seconds. 

If a connection is successfully made prior to the expiration of the seconds specified or the Cancel method is called, ConnectionTimeout has no effect. If the specified time expires and a connection has not been successfully made, the attempt is terminated and an exception is raised.
