There are unfortunately mannnnnyyyy warning and errors in the logs in a normal working Conan, so it’s always difficult to know what causes issues.
One thing you could try (just to eliminate some unknown parameters) is to disable the firewall on your desktop and laptop, see if you can connect: I’ve often seen a badly configured firewall block the return handshake so the connection never properly finishes. If that solves the problem, then try to add exclusions for both the server and client in your firewall.
