Telit - Listen Socket Problem

Hello,

I have a problem on the Telit - GL865 module for listen socket. I attached below some screen pictures about the comm. datas too… Module can connect to my pc easly(AT#SD). But i could not connect to it for listening socket(AT#SL). SRING message is not coming to accept the client(me)…

I review just one point, in the last weeks, when i power up the module, IP address was changing everytime, but it is not changing now…

What is my problem? may i have to set somethings in configurations but i couldnot find it related docs…
