Arduino ESP8266 AT+CIPStart Link Type Error

Hi,
i am using the SerialESP8266wifi.h library with Arduino UNO and ESP8266 module.
I uploaded the library example sketch into the Arduino.
I got link to WiFi network and got IP address just fine. also i ping it and got response.
While i'm trying to connect to server using connectToServer, i am receiving a message - Link Type Error in the serial monitor.
I succeeded to conect to the server same IP and Port using Hyper Terminal but still got the Error from the ESP8266 and Arduino.

any suggestions?
thanks in advanced.

Must be something wrong with your code. If only you had posted it...
