# License management

## On-premise licenses

In general, the on-premise deployment model requires your [**XMS**](#user-content-fn-1)[^1] to connect with the **Xopero ONE** license server <mark style="color:red;">**once every three days**</mark>.&#x20;

This process is performed automatically. If the device with **Xopero ONE** installed has no internet connectivity, you can configure the specified rules to allow the device to connect to the component listed in the below table.

| Component      | Port        | IP address      |
| -------------- | ----------- | --------------- |
| one.xopero.com | 443 (HTTPS) | 213.222.221.126 |

## License details

To view your license details, click ⚙ **Settings** at the bottom-right of the left-side menu, and select **License**.

In the **Manage license account** panel, you can check your license status, last verification time, validity period, number of licenses, and detailed information about each license. You can also force refresh your license if needed.

If the verification fails and your license package is not verified within three days, the **Management Service** may stop working.
{% endhint %}

## Force license refresh

**Xopero ONE Management Service** (**XMS**) allows you to refresh the license manually. This way, you don’t have to wait for the **Management Service** to refresh the license automatically— you can do it <mark style="color:$danger;">instantly</mark>. It may be useful, for example, when you increase the number of licenses.

To refresh your license, click ⚙ **Settings** at the bottom-right of the left-side menu, select **License**, then click **Refresh** button under the selected verified license package.
