I am getting No route to host errors on the server console on macOS

This issue happens with macOS Sequoia or later if you are using third-party terminal applications (iTerm, kitty or similar) and you have not allowed your terminal app to access the local network.

To fix this, go to System Settings > Privacy & Security > Local Network and allow your terminal application to access the local network. You will need to restart the terminal app after you have changed the setting.
