This guide covers every setting you can change on your FiveM server without touching code: the Server config page, the Startup variables and the Artifacts page for FXServer builds.

​
The Server config page

Server config shows your server.cfg in plain words. Only the lines you change are touched; everything else in the file stays as it is. Open your server, then click Server config in the sidebar under FIVEM.
Server config page with an Open txAdmin button, a Checks box with one item to look at, and the Your server section with Server name, Project name, Player slots marked your plan, Language and Licence key fields

The Server config page

If the Checks box shows txAdmin runs this server, txAdmin reads server.cfg from the folder you chose in its setup. Pick your server’s main folder there, or the changes on this page are not used. See Set up txAdmin.

Gameplay and security

Gameplay and security section with the OneSync selector set to On (recommended), a Game build drop-down, Allow Script Hook and Hide player IP addresses toggles, and a Server list section with Description, Tags, banner and server icon fields

​
Server list

A field marked not in the file has no line in server.cfg yet. Filling it in adds the line.
Cfx.re also lets you manage your server’s listing on portal.cfx.re. If the server list shows something different from what you set here, check your server’s details on the Portal too.

​
Save your changes

1

Review

Change the fields you want, then click Review and save in the bar at the bottom. Click Discard to undo everything instead.
2

Check the changes

Review your changes shows exactly which lines change in server.cfg. Licence keys, passwords and other secrets are hidden in this view.
Review your changes dialog showing the server.cfg lines that will change, a note that the old file is kept as server.cfg.bak, and Cancel and Save changes buttons

Review your changes before you save

3

Save

Click Save changes. The old file is kept as server.cfg.bak, so you can go back if needed.
4

Restart

Restart the server so the changes take effect.
Need a setting that isn’t on the page? Click Advanced: open the raw file to edit server.cfg directly in the file editor. The editor keeps earlier versions of the file; see how to use the file manager.

​
OneSync

According to Cfx.re, OneSync is free up to 48 slots. For more than 48 slots, your licence key needs a FiveM Element Club subscription from the Argentum tier upwards, bought on portal.cfx.re.

​
Game build

The game build decides which GTA V DLC content (cars, clothes, maps) your server can use. Every build includes everything from the builds before it.
  1. In Server config, open Game build and pick a build. Click Details for more about each option.
  2. Click Review and save, then Save changes.
  3. Restart the server. Players download the matching game data the next time they join.
Some resources need a minimum build, for example cars or clothing from a recent DLC. Check the resource’s instructions. For the full list of builds and their DLC names, see the Cfx.re server commands reference.
Only raise the build when a resource needs it. A higher build means a larger download for players joining for the first time.

​
Startup variables

Click Startup in the sidebar. Change a field and click outside it: it saves on its own. Restart the server to apply it. See how to configure startup variables. The Docker image (ghcr.io/luxxy-gf/pterodactyl-fivem) is the only one available, so there is nothing to choose there.

​
Player slots

Your player slots come from your plan. At every start, the panel writes sv_maxclients in server.cfg from Max Players, so any number you type into server.cfg by hand is overwritten.
  • To get more slots than your plan includes, upgrade your plan in the client area.
  • More than 32 players needs OneSync set to On, and more than 48 needs an Element Club subscription on your licence key (see OneSync).

​
Steam Web API key

Without a Steam Web API key, your server can’t see players’ Steam identifiers. Scripts that use Steam IDs for admin rights or bans then don’t work.
1

Get a key

Sign in at steamcommunity.com/dev/apikey, enter any domain name (for example your community’s website) and copy the key.
2

Paste it

In Startup, replace none in Steam Web Api Key with your key.
3

Restart

Restart the server.

​
Change the FXServer build

FXServer is the server program itself (often called the “artifact”). The Artifacts page lets you switch it in a few clicks, and go back if something breaks.

The Artifacts page

A badge such as YOUR BUILD or OLDER THAN YOURS shows how each one compares to what you run now.
1

Make a backup

Create a backup first, so you can undo anything that goes wrong.
2

Pick a build

Click Artifacts in the sidebar, then click Recommended, Latest or Pick a specific build.
3

Check the dialog

The dialog shows the build you run now, the build you picked and until when Cfx.re supports it. If you pick an older build, you see a warning that resources and txAdmin data made for a newer build may not work on it.

Change the build

Switch on Start the server afterwards if you want, then click Change Build.

​
What happens

  1. The new build is downloaded (about 70 MB) and checked while your server keeps running.
  2. The server is stopped.
  3. The server program is replaced. The old build is kept, so you can go back with one click.
  4. The server stays stopped until you start it (unless you switched on Start the server afterwards).
Your resources, server.cfg, txAdmin data, cache and logs are not touched. The switch takes about half a minute.

​
Go back to your old build

After a change, the Artifacts page shows who installed the build and when, and that the previous build is kept.
  • Click Go back to build … to switch back.
  • Click Delete it to remove the kept build once you’re happy with the new one.

​
Builds expire

Every FXServer build has an end-of-support date from Cfx.re, shown as until on each card. A build past its date may stop working. Check the Artifacts page now and then and move to Recommended before your build expires.

Getting started

Licence key, txAdmin setup and first connect.

Resources

Add and start scripts, cars and maps.

Performance

OneSync, hitch warnings and lag.

Troubleshooting

When changes don’t apply or a build breaks.
