How to Fix the 'FiveM License Key Invalid' Error

Understanding the Error

The "License Key Invalid" error typically appears when your FiveM server lacks a valid license key or the provided key is incorrect. The error message usually reads:

This server does not have a license key specified. Please set the sv_licenseKey console variable to a key from https://keymaster.fivem.net/.

Without a valid license key, your server won't start, as FiveM requires this key for authentication.

Step-by-Step Solution

1. Obtain a Valid License Key

   Visit the FiveM Keymaster website and log in with your Cfx.re account. If you don't have an account, create one. Once logged in, navigate to the "Servers" section and click "Create New Server". Enter your server's IP address and generate a new license key.

2. Update Your Server Configuration

   Access your server's configuration file, typically named server.cfg. Add or update the following line with your new license key:

   set sv_licenseKey "your_license_key_here"

   Replace your_license_key_here with the key you obtained in the previous step.

3. Restart Your Server

   After saving the changes to your server.cfg file, restart your FiveM server. This will apply the new configuration and should resolve the license key error.

Troubleshooting Tips

• Check for Typographical Errors: Ensure there are no spaces or incorrect characters in the license key.
• Verify Server IP Address: The license key is tied to your server's IP address. If your server's IP changes, you may need to generate a new key.
• Consult Server Logs: Review your server logs for any additional error messages that might provide more context.
