# 🚫 'Mismatched mod channel list' Error Type 🚫

This error can appear in your Minecraft client when you try to join your modded server.

The message means that there are differences between the server and the client `mods` or `config` folders.

||| [Here](https://help.ggservers.com/en-us/article/how-to-install-mods-on-your-server-1bauy2t/) is our guide for installing mods into your server and [here](https://help.ggservers.com/en-us/article/how-to-install-mods-into-your-client-1t47nya/) to one for installing them into your client.  
---

Also, please note that there is a category of mods called client-side mods, which needs to be set up only on your client, not on the server too. Some examples are `OptiFine` or any mini-map mod. Please be sure to not add any client-side mods to your server to prevent this type of error.

||| We have a guide explaining them [here](https://help.ggservers.com/en-us/article/client-side-mods-1f2zfxl/).

# ✔️ How to Solve ✔️

To solve this error and be able to connect to your server, you will have to replace the server `mods` and `config` folder with the local ones from your PC.

||| We suggest you start the process by backing up the world as our guide explains [here](https://help.ggservers.com/en-us/article/how-to-download-your-world-17ewr1r/) just in case.

You will have to do the following steps:

2. Connect via FileZilla to your server and rename your `mods` and `config` folder to `mods_old` and `config_old`. This way you also have a backup for those folders.
