Remmina connect from Ubuntu 22.04 Desktop PC (i.e. Client) to another Ubuntu 22.04 Desktop PC (i.e. Server) on LAN fails with "Could not find address for the RDP Server".

I've tried changing the Security Protocol Negotiation from Automatic to RDP Security Protocol Security, but same result. Port 3389 is Open for TCP on the Server.
The computer running the Remmina client cannot resolve the demonstrator.local name to an IP address. Simply use the
dig commands to check this.
dig demonstrator.local ping demonstrator.local

Then use that name without the "local" extension to connect:
