Hello, I have been getting an error message ever since I tried to game start my maple global client.

The message says :
we are unable to connect to the login server due to a server check, a firewall block or other network issues. Please check if the Maplestory homepage for ongoing server checks as well as your firewall settings.

I have checked my firewall settings, and tried turning it on and off. The game still shows the message above.

I am from Bangkok, Thailand. I tried to search online and check if Thailand was blocked by Maple Global. But I haven't seen one saying that it is blocked.

I'm not a pro technology person, so please do help me :)
Thank you.
