Are you here for the same reason? If yes then don’t worry we got you covered, in this guide we will provide you some effective solution to resolve this error.

What is FML in Minecraft?

FML in Minecraft stands for “Forge Mod Loader.” 

Forge is a popular modding platform that allows players to easily install and manage mods for Minecraft. 

Forge Mod Loader is a part of the Forge framework and is responsible for loading and managing mods within the game.

How To Fix Minecraft Incompatible FML Modded Server Error

The Minecraft Incompatible FML Modded Server Error is a common issue that occurs when you try to join a server that has different mods or mod versions than your game.

Here are some steps you can take to resolve the error:

Check Mod Versions:

Make sure that the mods you have installed on your client match the versions of the mods on the server. 

If there is a mismatch, you may encounter compatibility issues.

You can find the mods folder in your Minecraft installation directory, usually located at “%appdata%\.minecraft\mods” on Windows.

If you have any mods or mod versions that are different from the server, you need to delete them from your mods folder and download the correct ones from the internet.

Check Forge Mod Loader (FML) Version:

Confirm that both your client and the server are using the same version of Forge (FML).

If there is a version mismatch between the FML version on the client and the server, it can lead to compatibility issues and result in the “Incompatible FML Modded Server” error.

Download and install the correct version of Forge on your client. 

You can find the correct version on the official Forge website.

Confirm that the mods installed on both the client and the server are compatible with the version of Forge Mod Loader being used.

Check Server Mods:

Confirm that the mods installed on the server are designed to work with the specific version of Minecraft that both the server and clients are running. 

Mods depend on the game’s version, and using the wrong version may lead to compatibility issues.

Make sure that the server is running the same version of Forge or Fabric as the client. 

If the server is running an outdated or mismatched version, it can cause the “Incompatible FML Modded Server” error.

Visit the websites or forums where you downloaded the mods for the server. 

Mod developers regularly update their mods to be compatible with the latest Minecraft versions and fix any bugs. 

Download and install the latest versions of the mods compatible with your server version.

Additionally, confirm that the server has the mods installed in the correct folder. 

Mods are typically placed in the “mods” folder within the server directory. 

If the mods are not in the right location, the server may not recognize them.

Update Mods:

Make sure that all the mods you have installed are up to date. 

Mod developers regularly release updates to improve compatibility and fix bugs.

Using outdated mods can cause compatibility issues.

Visit the official Minecraft Mods websites or platforms like CurseForge to download the latest versions.

After updating the mods, restart both the Minecraft server and the client to apply the changes. 

This ensures that the updated mods are loaded properly.

Clear Mods Cache:

This can help resolve compatibility issues or errors that may arise from a corrupted cache.

Before proceeding, it’s a good idea to create a backup of your mods folder. 

Copy the entire “mods” folder to another location on your computer. 

This ensures you have a copy of your mods in case anything goes wrong.

Here’s how to clear cache:

  • Open your Minecraft installation directory. 
  • This is where Minecraft is installed on your computer.
  • Find the “mods” folder within this directory. 
  • This is the folder where all your Minecraft mods are stored.
  • Open the “mods” folder, and delete or move all its contents. 
  • This includes all the mod files and folders.
  • After clearing the mod cache, restart Minecraft.
  • Launch the game and attempt to connect to your modded server or start a single-player world.

Forge will automatically rebuild the mod cache when you launch the game. As you load into the game, it will detect the available mods and recreate the necessary files in the “mods” folder.

Once the game has loaded successfully, test your gameplay to see if the Incompatible FML Modded Server error or any other issues persist.

Reinstall Minecraft:

Reinstalling Minecraft removes the game from your system and then downloading and installing it again. 

This process can help ensure that any corrupted or conflicting files are replaced with fresh, working ones.
