# Complete setup of an Arma Reforger server

{% hint style="info" %}
Guided **crossplay** (PS5 / Xbox / PC).\
Key settings are done via `config.json`.
{% endhint %}

### 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

{% stepper %}
{% step %}
**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:

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

{% endstep %}

{% step %}
**Become an administrator (PS5 / Xbox / PC)**

In `config.json`, add or modify:

```json
"adminPassword": "yourpwd"
```

In-game, connect then type:

```
#login yourpwd
```

{% hint style="warning" %}
On console, do not add a SteamID to an `admins`.\
It can cause a server crash.
{% endhint %}
{% endstep %}

{% step %}
**Manage the AIs (bots)**

**Option A — Disable AIs**

In `config.json` :

```json
"operating": {
  "disableAI": true
}
```

Restart the server.

**Option B — Reduce AI difficulty**

Create or modify:

```
/profile/settings/ai.json
```

Example of easier values:

```json
{
  "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.

{% hint style="info" %}
If nothing changes, the file may be ignored depending on the mode.\
Test with "Conflict" or "Game Master".
{% endhint %}
{% endstep %}

{% step %}
**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.
{% endstep %}

{% step %}
**Fix an invisible server in crossplay**

In `config.json`, check:

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

Also check connectivity:

* UDP: `2001` to `2010` (game)
* TCP: according to your server's query port

{% hint style="info" %}
The listing may have a delay.\
Wait 1 to 5 minutes after a restart.
{% endhint %}
{% endstep %}
{% endstepper %}

### 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`.
