You should not have 192.168.1.1 as a DNS server for pfSense, though it would not break anything.
The server set in System > General Setup though are not used by Unbound in pfSense unless you have set the DNS resolver to forwading mode. By default it resolves directly.
However since it looks like you're passing 1.1.1.1 to the client directly it should be able to resolve whatever pfSense is doing so I'd look for error on the client. Try on the client:
