DNS unbound configuratino for local searx server?

[bread]

Hey there!
How can I resolve my local searx server just within internal network?

• I have myhostname.local in the /etc/nginx/sites-enabled/searx
• searx server is connected and can be reached, but shows just the welcome page of nginx
• connection via hostname within browser doesn't work

I suppose it has something to do with the unbound settings.

I use PiHole as DNS server for all clients, but PiHole uses OPNsense as upstream server.

Cheers
