Problem with TCP Client and server not present


I use “wip_TCPClientCreateOpts” to create a TCP socket client (plugin V5.10.0.2020 wip). If the server (and port) is present, I have no problem for connecting. The event “WIP_CEV_OPEN” is triggered. If the server is not active (or the port is not open), sometimes (randomly) no event timeout is triggered. The program remains “freeze” and no event is triggered. Could you help me? Thank you
