How to Fix TMODLoader Mod Browser Not Working on Windows 11: Step-by-Step Solutions

TMODLoader is a popular modding tool for Terraria that lets you easily manage and install mods. However, sometimes the Mod Browser in TMODLoader may stop working, especially on Windows 11. This can be frustrating if you want to add new mods or update existing ones.

Fortunately, there are several simple steps you can follow to fix this issue. These steps range from basic checks to more advanced troubleshooting methods. By following each step carefully, you’ll likely get your Mod Browser working again in no time.

This guide will walk you through the most common solutions in an easy-to-understand way. You don’t need to be a tech expert to follow along.

Let’s get started and fix your TMODLoader Mod Browser on Windows 11.

Quick Note: Prerequisites and Initial Checks

Before diving into fixes, make sure you have the following ready:

Stable internet connection: The Mod Browser needs to connect online to download mod data.
Windows 11 updates installed: Sometimes system updates fix compatibility issues.
Latest TMODLoader version: Using an outdated version may cause the browser to malfunction.
Terraria installed and updated: TMODLoader depends on Terraria’s files.

Step 1: Restart TMODLoader and Your Computer

This might sound too simple, but many software glitches are fixed by a restart. Close TMODLoader completely, then reboot your computer.

Restarting clears temporary files and resets network connections, which can help if the Mod Browser fails to load.

Step 2: Check Your Internet Connection and Firewall

Since the Mod Browser connects to online servers, a weak internet or firewall blocking TMODLoader can cause problems.

Follow these steps:

Make sure your internet is working by opening a web page in your browser.
Open Windows Security settings and navigate to Firewall & network protection.
Click on Allow an app through firewall.
Find TMODLoader in the list. If it’s not listed, click Allow another app and add it manually.
Ensure both Private and Public networks are checked for TMODLoader.

Allowing TMODLoader through the firewall ensures it can connect to mod servers without restrictions.

Step 3: Run TMODLoader as Administrator

Sometimes, TMODLoader requires extra permissions to access network features.

To run it as administrator:

Right-click the TMODLoader shortcut or executable file.
Select Run as administrator.

This grants TMODLoader the necessary rights, which can resolve access or permission-related issues with the Mod Browser.

Step 4: Clear TMODLoader Cache

Cached files can become corrupted and cause the Mod Browser to malfunction.

To clear the cache:

Close TMODLoader completely.
Navigate to the TMODLoader folder, usually found in Documents/My Games/Terraria/tModLoader.
Locate and delete the ModBrowserCache.json file.
Restart TMODLoader and check if the Mod Browser works now.

Deleting this file forces TMODLoader to download fresh data from the servers.

Step 5: Disable VPN or Proxy Services

If you use a VPN or proxy, these can interfere with TMODLoader’s connection to mod servers.

Try temporarily disabling your VPN or proxy, then restart TMODLoader and open the Mod Browser.

If this fixes the problem, adjust your VPN or proxy settings to allow TMODLoader traffic or use it without these services when modding.

Step 6: Update or Reinstall TMODLoader

Sometimes the issue is due to bugs in the TMODLoader version you’re using.

To update TMODLoader:

Open Steam and go to your Library.
Right-click TMODLoader and select Properties.
Go to the Updates tab and make sure automatic updates are enabled.
If you don’t use Steam, download the latest TMODLoader version from the official site and install it over your current installation.

If updating doesn’t help, try uninstalling TMODLoader completely and reinstalling it fresh. This can fix corrupted files causing the Mod Browser to fail.

Step 7: Check Terraria Installation Integrity

Since TMODLoader depends on Terraria, corrupted game files can cause issues.

To verify Terraria files via Steam:

Open Steam and go to your Library.
Right-click Terraria and select Properties.
Go to the Local Files tab.
Click Verify integrity of game files.

This process checks for missing or corrupted Terraria files and repairs them.

Advanced Option: Use Command Line to Launch TMODLoader

For more advanced users, launching TMODLoader with extra logging can help diagnose issues.

Open Command Prompt and navigate to the TMODLoader folder, then run:

tModLoader.exe -logFile

This creates a detailed log file that can help identify errors related to the Mod Browser.
