If it is failed, TCP connection also will be failed. And where does "fail to connect server" message come from? I think it is not from CSE-H53N. and if network is fine, please check STS led(on) and [STATUS] of ezManager. TCP state will be "Established" not "SYN_SENT". if state is syn_sent(trying to connect to the host), your sever is not ready. then please check your server. Here is a FAQ. <a href="http://www.eztcp.com/en/support/view.php?page=1&cid=286" target="new">ezTCP does not work! (Checklist)</a> please refer [2. Fail in TCP connection].
