This is not a digikam but a network problem. You cannot directly connect 
to a machine in another subnet than its own.

The easiest solution is to connect both computers to the same subnet 
(e.g. both same ethernet, or both same wifi).

If you can't, you need routing between the subnets and set up your 
router accordingly or add routes manually on the computers using the 
"route add" command.

You can also install Tailscale or ZeroTier on both computers; they 
connect regardless of subnets/firewalls.
Or use WireGuard: Lightweight VPN.
Or mDNS / Avahi: For hostname resolution (.local names) across subnets 
(install Avahi on Linux, enable Bonjour on Windows/macOS).

Search for your best solution in network manuals/forums for your 
operating system and router type.
