I'm using 2021-01-07a client and it worked just fine when I connect to my server locally. So I set up a server at a different computer, changes the IP in the sclientinfo.xml to that different computer's IP.
But it fails to connect to server after Select Service. I can login to my character and it showed the usual Select Service, but after clicking that, it get stuck in the "Please Wait" window, before giving a message "Failed to Connect to Server."
What puzzles me is that when I tried to use a different client, this time I used 2021-11-17 client (it was included in Anacondaq's Offline RO pack) and it worked. I connects to the game after the Select Service and the Character Selection Menu shows up.
I hope someone out there can solve my problem.
