Client Citect SCADA cannot connect to server

Hi all

I tried to connect Citect SCADA Client to my Server.

The client hardware alaram shows "No IO Server Could Be found" same the thing for server Alarm and Report.

i find some document that say if you get "No IO Server Could Be found"  you should open ports (2082, 2083...) in the fire wall to connect client to the server. I tried to connect to IOServer Port 2082 Via Telnet but it dosent work.

When i usethis command on the server: Telnet 127.0.0.1 2082 its fine but when i change 127.0.0.1 by The server IP adresse 192.168.10.112 on the same machine its not working. i disabled the firewall but still not working. Then i made my local network private but still not working.

Can you plz help me

Thank you all
