# Cloud licence disconnected

If your cloud licence disconnects, open CodeMeter Control Center (on the server machine if the licence is hosted on one) and in the **License** tab, check that there is at least one entry like the one shown below.

If an entry exists, please check that the the CmCloud URL is **https://wibu.cloud/74447** and the status is **Connected**.

If the status does not list **Connected**, please go to the Events tab in Codemeter Control Center and search for any of the following error messages.

- *CmCloud(Curl) : error code: 60* **or** *35: SSL certificate problem: unable to get local issuer certificate.* If this message exists, you will likely need to add a whitelist for **https://wibu.cloud/74447**. The issue occurs due to a proxy or some firewall breaking open the encryption.
- *CmCloud(Curl): error code: 6: Could not resolve host: wibu.cloud.* This suggests a firewall issue. Please consider whitelisting **https://wibu.cloud/74447.**
- *CmCloud(Curl) error code: 28.* Please make sure that your CodeMeter User Runtime is 7.60 or later. You can download the latest version [here](https://www.wibu.com/support/user/user-software.html).

If other error messages exist, please contact our [support team](mailto:support@floodmodeller.com).

Please note that the URL **https://wibu.cloud/74447** is not accessible through a browser or postman. If you would like to test the connection, please open a Windows Command Prompt and run the following:

```powershell
curl -X POST https://wibu.cloud/74447
```

For systems without [cURL](https://curl.se/docs/), a Powershell alternative is available:

```powershell
Invoke-RestMethod -Uri "https://eu-backend.wibu.cloud/74447" -Method Post
```

The expected return value in both cases is: `CmCloud!`

This confirms the system is configured correctly to communicate with WIBU’s servers.

### Whitelisting cloud server

Depending on the firewall policies imposed by your IT department, you may need to whitelist “eu.wibu.cloud” (preferred) or “(*).wibu.cloud”.

Please do not try whitelisting the IP associated with “wibu.cloud” as it is dynamic and changing without prior notice.
