+# Windows 365 Link connection fails with "Cloud PC does not support Entra ID single sign-on"
+
+After a user authenticates on the sign-in page, when the user tries to connect to the Cloud PC, the user might encounter the following message:
+
+> Something went wrong.  
+> Your Cloud PC does not support Entra ID single sign-on.
+
+## Cause
+
+This error commonly occurs when single sign-on (SSO) isn't enabled.
+
+## Resolution
+
+Windows 365 Link requires that [SSO is enabled on the Cloud PC](/windows-365/link/requirements) it connects to.
+
+To confirm the status of SSO on the Cloud PC, follow these steps:
+
+1. Sign in to the [Microsoft Intune admin center](https://go.microsoft.com/fwlink/?linkid=2109431).
+2. Navigate to **Devices** > **Device onboarding** > **Windows 365** > **All Cloud PCs**.
+3. Select **Columns** > **Using single sign-on**.
+4. Search the list for the Cloud PC in question by device name or the user's User Principal Name (UPN).
+5. If **Using single sign-on** shows **No**, Windows 365 Link can't connect to it.
+
+## Reference
+
+For details on how to enable SSO on Cloud PCs, see [Configure single sign-on for Windows 365 using Microsoft Entra authentication](/windows-365/enterprise/configure-single-sign-on).
