tModLoader is a free, separate game on Steam for anyone who owns Terraria. Players join your server from tModLoader, not from Terraria itself.
Your server's address (its IP and port, such as 203.0.113.25:7777) is at the top of its page in the control panel.
- Start tModLoader and choose Multiplayer, then Join via IP.
- Pick the character to play.
- Type the server's IP (the part before the colon), then the port (the number after it, often
7777). - If the server has a join password, type it when asked.
You don't need to install the server's mods yourself: tModLoader downloads them as you join.
Can't join?
- Version mismatch: your tModLoader and the server must be the same version. Steam keeps your game on the newest stable release; to update the server, open the Updates tab and click Install next to tModLoader (latest release). If you play the preview branch in Steam, switch back to the stable one.
- A mod fails to load: mods need the tModLoader version they were made for. Check the Console tab for the mod's name, and remove or update it on the Mods tab.
