This tells the client to prefer that port for direct connections.
This is one of the most for relayed tunnel issues, especially when peers are behind routers with poor NAT support.

A relayed tunnel means your traffic is bouncing through Hamachi's servers instead of connecting directly to your peer. This causes high latency and lag.
If you still see "Relayed" after two hours of troubleshooting, accept that your ISP or router hardware is incompatible with Hamachi’s hole-punching algorithm. At that point, either use the VPN-over-VPN bridge or migrate to a modern mesh VPN like Tailscale. Click OK and restart Hamachi
