Hi, ive made a server for an instant messenger and created the server sockets, which was working fine, however when i attempted to use ssl (jsse) security i keep coming across the following error when running the code:
Thread exceptionjava.net.BindException: Address already in use: JVM_Bind
ERROR CLOSING SOCKET
