Resolving Common FiveM Errors (and What They Actually Mean)

FiveM error messages are written for developers. The good news: most of them say a lot more than they look like they say once you know what to look for.

Connection rejected by server

Almost always: your endpoint isn't reachable, or your license key is bound to a different IP. Check endpoint_add_tcp/udp and the keymaster panel for license bindings.

Script timeout: Above usage threshold

A specific resource is hogging the main thread for too long. Run resmon, find the offender, restart it. Usually caused by an infinite loop with no Wait(), or a SQL call that is blocking on a missing index.

Could not find dependency X for resource Y

Your fxmanifest.lua lists a resource that isn't loaded yet. Check your server.cfg order — ensure lines run top to bottom, and dependencies must come first.

Couldn't load resource X with no specific reason

Usually a file path issue inside the manifest, or a syntax error in the resource's main Lua. Open the file, check for an unclosed string or function, and try again.

OneSync is not enabled on this server

You are trying to use a OneSync-only API without enabling OneSync. Set set onesync on (for under 32 players) or set onesync_population true (Infinity).

VAR_NUMBER or weird game build errors

Asset that is part of a newer GTA DLC than your enforced game build allows. Update your sv_enforceGameBuild to match the asset's required build, or remove the asset.

Wrapping up

The pattern across all of these: the message tells you the symptom, the surrounding context tells you the cause. Don't paste the error into a Discord and wait — read the lines around it in the server console first. You will fix half of them yourself.
