I've configured the VPN Client and it connects to my OpenVPN server. I've configured the VPN client so that only 2 devices on the network us it. Initially everything worked fine but today DNS requests stopped working. Ping and tracert works successfully if you specify an IP address but not if you specify a hostname.

I've removed my laptop form the VPN client list on the Deco, configured OpenVPN client on the laptop and connected it to my OpenVPN server - DNS works perfectly.

My primary and secondary DNS are 1.1.1.1 and 1.0.0.1.

Any ideas why DNS requests and not working over the VPN
