# Fix Your System Clock

*Loaders verify your license against their servers, and that check fails if your Windows clock is out of sync — even by a small amount. The errors this causes almost never mention time, which makes it easy to miss.*

{% hint style="info" %}
**Fix your clock if:**

* The loader **closes immediately** without showing any error
* Login fails with a **generic "Error"** and no details
* Authentication fails even though your **license key / credentials are correct**
  {% endhint %}

{% stepper %}
{% step %}

### Open Date & Time Settings

1. Right-click the **clock** in your taskbar
2. Select **Adjust date/time**
   {% endstep %}

{% step %}

### Sync Your Clock

1. Make sure **Set time automatically** is turned **On**
2. Make sure **Set time zone automatically** is turned **On** (or your time zone is correct)
3. Click **Sync now**
4. Verify the displayed time is correct and the sync reports success
   {% endstep %}

{% step %}

### Restart the Loader

1. Close the loader **completely**
2. Open it again and log in
   {% endstep %}

{% step %}

### Still Failing? Restart Your PC

If the loader still won't authenticate after syncing, restart your computer and try once more.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
**Clock keeps drifting back?** Your motherboard's CMOS battery may be dying — the clock resets every shutdown. Replace the battery, or re-sync before each session. If authentication still fails with a correct clock, create a ticket in our [Discord](https://ssz.gg/discord).
{% endhint %}
