Just got myself a RT-AX88U and installed firmware 384.19. Set up DDNS and enabled OpenVPN server. Set "Client will use VPN to access" to Both. Exported config file and imported to Android. My phone is able to connect to the OpenVPN server and accessed internal resources. Using my phone's browser, I am not able to connect to any internet sites, getting the error message " <site>'s DNS address could not be found". Any ideas?
