Connect domains and manage ports
Use a free hostname or custom domain and share the correct Terraria port.
Connect with the displayed address
In PC Terraria or tModLoader choose Multiplayer → Join via IP. Enter the hostname, then the separate port shown under Server, Domains or Ports. Do not assume port 7777. AppLaunch reserves a unique node port for every server.
Free hostname
Open Domains, choose an available label and click Create free hostname. The dashboard shows the exact assigned hostname. Development hostnames stay in the development DNS namespace. DNS propagation can take time. Always share the port too.
Custom hostname
Enter your hostname under Domains → Custom hostname, connect it, and add the ownership TXT record displayed. At your DNS provider create an A record for that hostname pointing at the node IP shown in AppLaunch. Use DNS only if you use Cloudflare: the ordinary HTTP proxy does not carry Terraria game traffic.
Terraria does not use Minecraft's _minecraft._tcp SRV record. No web SSL certificate is needed for the game connection. A domain does not replace the assigned port.
Additional ports
Open Ports to review the managed primary allocation and request or remove additional TCP, UDP or combined allocations. Five additional ports are included in each plan. Configure compatible extensions to listen on their assigned container port. Allocating a port does not automatically make an extension listen. You cannot remove the primary game port through additional-port controls.
