MU SS9, can not go to all maps in Siege Server

Dear all,

Before resetting the server on VPS, I could go to Barrack, Crywolf (Siege Server) as well. But after resetting the server I could not go to those maps anymore, the error as the image.

I also try with my server on Vmware, that was okay.
So do I have to take care anything with Siege server on the VPS.

Thanks and Best Regards,

I could solve it as well, just because IP configuration.
