Troubleshooting
The most common problems people hit migrating to FiveM Enhanced, with the fix for each. If your issue isn't here, check the Legacy vs Enhanced reference — most migration errors trace back to one of the documented breaking changes.
Server startup
Startup .bat / hosting panel can't find the server (references FXServer.exe or server.7z)
The files were renamed. Update your scripts:
- Archive:
cfx-server_win_x64(Windows) /cfx-server-linux_x64(Linux) - Executable:
cfx-server.exe(wasFXServer.exe)
"Server specified an invalid game build enforcement"
Only the latest gamebuild (Kortz Center Heist) is supported on Enhanced. Old pins (2802 / 3095 / 3258…) don't carry over. Set a valid enforcement in your startup command, after +exec server.cfg:
+set sv_enforceGameBuild 11 selects the DLC-free base game; otherwise use the latest supported build number.
Old server.cfg tuning appears to do nothing after migrating
Several convars are deprecated or no-op on Enhanced. Replace / remove them:
sv_useAccurateSends→set sv_syncTickRate 60(range 1–120)sv_protectServerEntities→setr sv_entityLockdown "relaxed"- Remove:
sv_netHttp2,onesync_automaticResend,onesync_enableBeyond,sv_enhancedHostSupport
Resources
A Lua resource silently fails to load or throws Lua errors
Add lua54 'yes' to that resource's fxmanifest.lua. Lua 5.3 was removed in June 2025, so any script missing this line is already broken (on Legacy too). lua54 also unlocks the integer type, bitwise ops, and const/close attributes.
C#/.NET resources won't load on the Cfx Server
Install the .NET 10 SDK and rebuild the resources against .NET 10. Mono is gone, so old Mono-compiled assemblies won't load.
Escrow-protected / paid scripts don't work
Asset Escrow is not implemented yet in early access. Escrow-protected (encrypted) resources — including paid Tebex scripts — can't be relied on. Keep them on a Legacy server until escrow support ships for Enhanced.State bag values aren't syncing to clients like they used to
Behavior changed: on Enhanced, replicated values are only replicated if explicitly set, and state bag callbacks only fire if the entity exists. Code that relied on Legacy's implicit replication must now set replication explicitly.
Remote / console command output no longer shows on the client
Remote commands no longer return the full log to the client automatically. Call PrintRemoteCommandLog(message) in your handler where you want output surfaced.
Assets (Alchemist)
Alchemist GUI aborts partway through converting a folder
It hit an escrowed asset — the GUI fails and stops on the first one. Either remove escrowed assets first, or use AlchemistCli.exe, which skips them automatically and lists them in the output report. See Convert Assets with Alchemist.
A converted vehicle/prop is broken, invisible, or won't spawn
Re-convert without --relaxed (relaxed mode's auto-fixes can alter assets). If the source was made with an old tool, try --refine to correct formatting first. Always test converted assets in-game before deploying.
Voice
pma-voice works now but I'm told it will break
It relies on deprecated Mumble natives that only work because they temporarily route through the new voice system. They'll be removed in a future version. Plan a migration to the new server-side Voice API (docs). Note: pa-radio isn't referenced in official docs.
Client
Errors like "GTA5.exe not found" or "GTA 5 Enhanced not supported"
Most of these are pre-launch messages (2025–early 2026) from before FiveM supported Enhanced. As of July 21, 2026, use the dedicated "Download FiveM for GTAV Enhanced" installer with an owned GTA V Enhanced PC copy (Steam/Epic/Rockstar). Treat older dated search results with caution. See Install the Client.
My Enhanced client can't join a server / says wrong version
Enhanced and Legacy are not cross-compatible. An Enhanced client only joins Enhanced (Cfx Server) servers; a Legacy client only joins Legacy servers. Launch the client that matches the server.
