Client Cant connect LAN error, Solved!

Hi everyone just wondering if any of u could help me with some troubles i have with my server, when i open the client and try to connect is comes up with the "Cant Connect" error I've tried a few thing already and still the same, it would come to the screen to select server and then wont do anything or u can log in with any letters and any pw and then wont do anything, any help really appreciated thanks in advance.

Update: Thank's to @noesis123 for his help :laugh:

Now i can connect locally :thumbup1: i mean in server pc and same as client

Now i want to connect LAN,
Solved:
I config my files with server LAN ip and add 1 1 in DBSRV and Zones Serverlist.txt, Client Serverlist 0 6 also add client and server ip to Admin.txt in DBSRV, remember edit client hex HTLauncher(CFF Explorer) and HTMessege.xml with lan server IP and copy DBSRV Serverlist.bin to client.

Serverlist's e.g. :

Server Zones and DBSRV
1 1
0 192.168.0.x 1000
0 192.168.0.x 3001

Server DBSRV\Admin.txt
0 192.168.0.x <server lan ip for GMtool and/or local client
1 192.168.0.x <Client ip

Client
0 6
0 192.168.0.x 1000
0 192.168.0.x 3001
