OpenVPN Client cannot connect to internet

[blade117runner]

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?

After flashing the RMerlin firmware, did you do a full reset to factory defaults?

I didn't, thinking I only configured the Network SSID at that stage. The router was new.

You must. Many changes going from stock to RMerlin firmware (and vice versa).

Just restored to factory defaults, redid my settings, re-exported and re-imported config. Same issue. Not sure if it is relevant but when I enabled up the OpenVPN server, it was stuck spinning for "Export OpenVPN configuration file". I rebooted the server and the vpn server was then up running.

If you re-imported an old backup config file, you effectively undid the full reset.

Try again.

See the link in my signature below for the M&M Config for further suggestions on getting the router to a good/known state.

Sorry I meant I re-exported the OpenVPN config and re-imported back to my phone. The config on the router was all redone manually.

Did you set 'Advertise DNS to clients' to 'Yes', in the Advanced Settings?

That's it! Can't thank you enough for helping a newbie like me

You're welcome. I'm sorry I didn't think of that option to check sooner!

But, you won't regret doing the full reset in the long term.
