GL-SFT1200 opal vpn does not resolve when connected

When I connect to router, which is setup as a repeater internet works fine. I enable vpn client (windscribe pro) and unable to access websites other than google and search which works fine.

I am able to ping 8.8.8.8 and 1.1.1.1 successfully with no packets lost. Seems like a DNS issue but I am not sure how to resolve.

Thanks

In this case, you can just set up google (8.8.8.8, 8.8.4.4 or 1.1.1.1) in the custom dns server settings on the router and try.
