Having trouble connecting from China on Asus Router

[Social_House 0]

Hi team,

Thank you for the great service! I've been using AirVPN and it has been very stable. 

I used a Asus router and use OpenVPN there. It works fine for a couple of month. However, today it started not connecting. I've tried multiple config and all of them don't work. Would you please help me take a look on what's happening? Thank you so much!

Best wishes

The error is quite clear:

Jul 25 20:11:22 ovpn-client3[27421]: RESOLVE: Cannot resolve host address: america3.vpn.airdns.org:443 (Name or service not known)

What are the current DNS settings on the box?
