```
Unable to login with Microsoft Entra ID. Please contact your administrator. Error: Object reference not set to an instance of an object.
```

### Solution

{% hint style="success" %}
The Access URI is case sensitive and must respect the certificate host name.
{% endhint %}

To solve these issues, verify that the Access URI is properly set in the IIS tab of the Devolutions Server settings. Please see [Access URI](https://docs.devolutions.net/server/kb/knowledge-base/access-uri/) for more information.
