Can't enter maplestory reboot from Singapore

I have downloaded nexon laucher and maplestory reboot NA, however they keep saying I’m in a different region so I cant enter, but my full VPN is on, the fastconnect mode is on. I think the TAP-Win32 driver isn’t working as well. I have been searching for ways to work the driver but none of them works? Everything is just so confusing, please help

@yalahyalah Are you meaning that How to check the basic functionality doesn’t work for you?
