VPN Ping Error

I used to connect the this ISP mail.global.net.pg but when I subscibed to their VPN service and been connecting for sometime.

Now I realized that I cannot access www.global.net.pg unless I connect to the VPN. Previously, I do not need to be connected to the VPN to access www.global.net.pg…

Has the VPN affected by connection protocols?

Appreciate your help?
