Last reviewed: June 2, 2026

We’ve put together this quick and helpful guide to cover the most common FiveM errors and the usual suspects behind them. This doc is meant to save you time, frustration, and a few too many Google tabs.

Please Note:

  • This guide is provided as a courtesy — we do not offer support beyond what’s listed here.
  • If the solutions we’ve provided don’t work for you, unfortunately, that’s all we’ve got. (Unless stated otherwise inside the guide page).
  • If your issue isn’t listed here… then it might not be so common.
  • If you need further assistance, please feel welcome to reach out in the Project Sloth support channel.

We kindly ask that you do not open support tickets or reach out for help regarding the issues covered here — such requests will be automatically closed without response, or you may just find yourself right back here. That being said... Use it, bookmark it, share it — just don’t ask us for help beyond it. Thanks!

Thank you for understanding, and we hope this guide serves you well!
