OpenVPN client can't resolve hostname, DNS query denied

Hi Guys,
I recently setup a pfSense firewall and everything is working fine. I enabled the OpenVPN last night and client can connect.
Only issue is that client computer (windows 10) can access the Lan resourse via IP but not Hostname.
I am using the Local pfSense IP address as the DNS for remote client. Anything missing?

Thnaks!

In the OpenVPN RAS Advanced Client Settings push your pfSense IP as DNS again together with Force DNS cache update:

You also need a Firewall Rule for the OpenVPN Client to reach pfSense DNS. For testing best practice is to put some any-any Rule in the OpenVPN Firewall tab. Once you have everything working tighten your Rules.
