Hello.

Please make network CSE-H53N and Host properly.

Ping test must be successful.

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.
ezTCP does not work! (Checklist)

please refer [2. Fail in TCP connection].

Thank you.
