How to Fix “Couldn’t Load Resource ox_inventory” in FiveM?

The FiveM error “Couldn’t load resource ox_inventory” typically occurs when the game fails to download or access the files needed to run the inventory system. This issue can originate from:

  • Server misconfigurations (e.g., corrupted files or hosting issues)
  • Client-side problems (e.g., poor internet connection or blocked downloads)

Below, we’ll break down the root causes and provide simple solutions to fix the issue.

Solutions for Server Owners

1. Restart the Server

Sometimes, temporary glitches during server startup can prevent resources like ox_inventory from loading properly. Restarting the server refreshes all processes and ensures resources reload correctly.

  • Shut down the server using your hosting panel.
  • Wait 2-3 minutes, then re-start it.

2. Re-upload ox_inventory Files

If the files are incomplete or corrupted during the upload process, FiveM won’t be able to read them, triggering the error. To fix this, replace the faulty files with a fresh copy.

  1. Access your server files (e.g., via FTP or your hosting dashboard).
  2. Delete the existing ox_inventory folder.
  3. Upload a new copy from the official source or your backup.
  4. Restart the server.

3. Check Server Logs

Server logs often reveal hidden issues, such as missing dependencies or permission errors, that might be blocking ox_inventory from loading.

  1. Open your server’s log files (usually located in the resources or logs folder).
  2. Look for lines mentioning ox_inventory or CURL error 18.
  3. Search online for any specific error codes to find targeted fixes.

Solutions for Players

  • Check Free Disk Space: FiveM downloads and stores resource files (like ox_inventory) on your drive. If your drive is nearly full, the game won’t be able to save these files, leading to the error.
    • Right-click your drive (e.g., C:) > Properties to check free space.
    • If you have less than 10GB of free space, delete unused files or move them to an external drive.
  • Run FiveM as Administrator: Some files require elevated permissions to download or modify. Running FiveM as an administrator ensures it has full access to your system, preventing permission-related errors.
    • Right-click the FiveM shortcut > Run as Administrator.
  • Check Internet Connection: FiveM requires a stable internet connection to download large resource files. If your connection drops or slows down, downloads may fail midway.
    • Test your connection: Open YouTube or Netflix. If videos buffer, reboot your router.
    • Run a speed test. For gaming, aim for:
      • ≥5 Mbps download speed
      • Latency (ping) ≤50 ms
      Speed test example
      Use Speedtest.net to diagnose connection issues.
    • Close bandwidth-heavy apps like Steam updates, Dropbox, or torrents to free up bandwidth.

If none of these basic fixes work, try the advanced solutions below.

1. Clear FiveM Cache

Corrupted cache files can prevent FiveM from downloading fresh resources by “trapping” outdated data.

  1. Close FiveM via Task Manager (Ctrl + Shift + Esc).
    Task Manager example
    Ensure FiveM isn’t running in the background.
  2. Navigate to FiveM’s install folder (right-click shortcut > Open File Location).
    File location example
    Access FiveM’s installation directory.
  3. Delete the cache folder inside the Data directory.

2. Temporarily Disable Firewall/Antivirus

Overprotective security software may block FiveM’s files, mistaking them for threats. Temporarily disabling your firewall or antivirus can resolve this issue. After testing, re-enable your security tools and whitelist FiveM to prevent future problems.

  1. Go to Control Panel > System and Security > Windows Defender Firewall. Firewall settings
  2. Turn off the firewall for Private and Public networks.
    Disable firewall
    Disable firewall temporarily to test.
  3. If the error disappears, whitelist FiveM permanently.

3. Use a VPN

Sometimes, ISPs throttle gaming traffic or route it inefficiently, causing timeouts. A VPN creates a direct, unthrottled connection to the server by encrypting your traffic and routing it through a private network. This prevents your ISP from interfering with your connection, ensuring smoother and more stable downloads.

  1. Install a trusted VPN like NordVPN (free trials work).
  2. Connect to a server near your physical location. VPN example
  3. Launch FiveM and try joining again.

If the error persists, contact the server admin—they may need to update resources.
