Game freezes when I select a server

I managed to log into the server which is in the same LAN, however when I select the server, the game freezes and after a while it returns with an empty channel list.
When I run Pangya on the server, it works perfectly fine.
The server is under a NAT setting. I've port forwarded 20201 10103 and 7911.
Any help is greatly appreciated

I found the problem.
I run my server inside a VM, and turns out that the guest OS has to be in the same 192.168.x range as the host.
good luck:lol:
