In a java application (client / server), with apache and https connecting, I have a connection problem. This is the error I received in the client part:

We have installed this software on many computers, and only the computer will tell me about this error. This computer has Windows 7 and Java 1.6.0_39 (32 bits). Could you help me find this error? (If you need more information, please let me know)
