FiveM: CURL error 18 when connecting
Fixable on your PCCURL error 18
A download from the server stopped partway through. Usually a corrupt cache file or a network hiccup.
Why it happens
Error 18 means the connection closed before the whole file arrived. Bad cache entries, DNS problems, or a VPN can all trigger it.
How to fix it
- Clear the FiveM cache folders ('cache', 'server-cache', 'server-cache-priv').
- Switch to a public DNS (for example 1.1.1.1 or 8.8.8.8) in your network adapter settings.
- Turn off any VPN or proxy and reconnect.
- If you're on Wi-Fi, try a wired connection to rule out drops.
Still broken?
If it only happens on one server, their file host may be overloaded — try again later or tell their staff.
