🖥️Complete setup of an Arma Reforger server

Step-by-step guide to configure an Arma Reforger server (admin, AI, crossplay, visibility, console mods).

Guided crossplay (PS5 / Xbox / PC). Key settings are done via config.json.

Objective

Set up an Arma Reforger server to:

• give you rights admin

• manage the AI (disable or reduce difficulty)

• understand the limits mods on console

• fix the visibility in crossplay

Step-by-step guide

1

Change settings via config.json

In some cases, the Advanced settings are not saved. Then use the file config.json.

Example of a basic configuration:

{
  "name": "[FR] Arma Reforger Server",
  "adminPassword": "mypassword",
  "operating": {
    "disableAI": false
  },
  "crossPlatform": true,
  "supportedPlatforms": ["PC", "XBL", "PSN"],
  "visible": true
}

2

Become an administrator (PS5 / Xbox / PC)

In config.json, add or modify:

"adminPassword": "yourpwd"

In-game, connect then type:

#login yourpwd

On console, do not add a SteamID to an admins. It can cause a server crash.

3

Manage the AIs (bots)

Option A — Disable AIs

In config.json :

"operating": {
  "disableAI": true
}

Restart the server.

Option B — Reduce AI difficulty

Create or modify:

/profile/settings/ai.json

Example of easier values:

{
  "aimingAccuracy": 0.2,
  "aimingShake": 0.6,
  "aimingSpeed": 0.4,
  "spotDistance": 0.5,
  "spotTime": 0.3,
  "commanding": 0.3,
  "courage": 0.4,
  "reloadSpeed": 0.6,
  "general": 0.4
}

Restart the server.

If nothing changes, the file may be ignored depending on the mode. Test with "Conflict" or "Game Master".

Mods on console: what you need to know

Mods are not compatible with PS5/Xbox for now.

Common reasons:

• main source: Steam Workshop

• loading often dependent on the PC

Tip: prefer modes/missions without mods if you are on console.

5

Fix an invisible server in crossplay

In config.json, check:

"crossPlatform": true,
"supportedPlatforms": ["PC", "XBL", "PSN"],
"visible": true

Also check connectivity:

• UDP: 2001 to 2010 (game)

• TCP: according to your server's query port

The listing may have a delay. Wait 1 to 5 minutes after a restart.

Common issues

• Server crash after becoming admin : remove any config like admins on the console side.

• Server visible on PS5 but not PC/Xbox : check supportedPlatforms.

• AIs remain “too strong” : check the path /profile/settings/ai.json.

• AI settings are not applied : change the game mode to test.

FAQ

Do I need to restart after modification?

Yes. Do it after each change to config.json or ai.json.
