# Common errors

## ❗️"You Lack the Required Entitlement"

If you've seen the following message in your **server console**:

```
You lack the required entitlement to use noxen_ox_inventory
```

Don't worry — this is a common issue when using **escrow-protected (FXAP)** scripts on a FiveM server.

***

### 🧠 What Does It Mean?

This error means that the **server you’re running the script on is not authorized** to use that asset.\
It usually happens when:

* The **script is not linked** to your server key
* The **wrong CFX account** owns the server or the script
* The **script was installed before being transferred properly**

***

### ✅ How to Fix It

Here’s a checklist to help you resolve it:

#### 1. Check Keymaster Ownership

Make sure the **CFX account** that owns the script also **owns the server key** you’re using.

> 🔗 [Go to Keymaster](https://keymaster.fivem.net)

***

#### 2. Check Asset Ownership

Visit the **Granted Assets** page and confirm the script is listed under your account:

> 🔗 <https://keymaster.fivem.net/asset-grants>

If the script isn’t there, you may have:

* Purchased it with the wrong account
* Forgotten to transfer it

➡️ See How to Transfer Assets

***

#### 3. Restart the Server

After confirming everything:

* Ensure the script is in your resources folder
* Make sure `ensure rsd_pain` is correctly placed in your `server.cfg`
* Restart your server

***

### 🔁 Still Not Working?

If you've verified everything and still see the message, try:

* Re-downloading the script from Keymaster
* Clearing your server cache
* Double-checking that the resource wasn’t renamed

***

### 🆘 Need Help?

Open a ticket on our Discord and provide:

* The name of the resource
* Your server license key
* A screenshot of the error

{% hint style="warning" %}
Note: You **must use the original folder name** provided with the script (e.g. `noxen_ox_inventory`). Renaming escrow-protected resources can break entitlement verification.
