1. Switch Off The Games Running In The Background

If you have other games running in the background, your Terraria might not work properly. As a result, you get this Terraria lost connection warning on your screen. Therefore, you should check first if other games are running in the background and if yes, close them.

This is a kind of bug that still exists despite frequent updates.

2. Check For The Latest Version Of The Game

This is another common issue with most users. If you’re using an outdated Terraria version, be ready for the lost connection issue and other bugs. Hence upon receiving this error, you must close the game and immediately update it if it’s due. 

Tip: You and all of your friends must also use Terraria’s updated version. 

You can update the game by following the steps mentioned below. 

  • Open the Steam Library.
  • Right-click on Terraria
  • Select Properties.
  • Click on the Local Files Tab.

It will solve your issue with the latest version. And if not, then you were already using the latest version, and it might not be the reason behind this issue. 

3. Check If You’re Playing Different Styles

If your character and map don’t coordinate with each other, you’ll also get the “Terraria lost connection” warning on the screen. For the classic Map or Classic mode game, a classic character is required, and like this, a journey character is required for a journey map.

If you use a classic character for a journey map, you might see this warning on the screen. Hence, make sure you build a character accordingly, and this warning will never arise in the first place.

4. Deactivate Windows Firewall

The following steps should be followed to deactivate it. 

  • Open the Start Menu.
  • Search for Windows Defender Firewall and press the Enter key.
  • Click on Turn Windows Defender Firewall on or off.

It can be updated in two ways – manually and automatically. If you have a vast knowledge of this, you can go for the manual update; otherwise, choose the automatic option.

6. Enable Port Forwarding

7. Uninstall And Reinstall Terraria

Steps for this are: 

  • Press the Windows + R keys on your keyboard. This will open the Run box. 
Run box
  • Type appwiz.cpl and press the Enter key or click on OK.
