 |`Bad request`|400|Possible cause: The resource name (SQL Server instance or database name) doesn't conform to Azure resource naming conventions. For example, if the database name is a [reserved word](/azure/azure-resource-manager/troubleshooting/error-reserved-resource-name).|
 | `Unauthorized` | 401 | Likely cause: the extension is configured to send data through an HTTP proxy that requires authentication. Using an HTTP proxy that requires authentication is not currently supported. Use an unauthenticated HTTP proxy or no proxy.|
-| `Forbidden` | 403 | If the Azure Connected Machine agent is otherwise working as expected and this error doesn't resolve itself after a reboot, create a support case with Microsoft Support through the Azure portal.|

If the Azure Connected Machine agent is otherwise working as expected and this error doesn't resolve itself after a reboot, create a support case with Microsoft Support through the Azure portal.|
 | `NotFound` | 404 | The endpoint that the extension is trying to connect to doesn't exist. <br/><br/> To check which endpoint it is trying to connect to, search the logs for `dataprocessingservice`. This condition can happen if the Azure Connected Machine agent was deployed and connected to an Azure region in which the `Microsoft.AzureArcData` resource provider is not yet available. [Redeploy the Azure Connected Machine agent](/azure/azure-arc/servers/manage-agent?tabs=windows#uninstall-the-agent) in a region that the `Microsoft.AzureArcData` resource provider for aSQL Server enabled by Azure Arc is available. See also [Region availability](https://azure.microsoft.com/explore/global-infrastructure/products-by-region/?products=azure-arc).<br/><br/> It is possible that the DNS resolver cache is not refreshed for your machine. To refresh: <br/> - On Windows run: `ipconfig /flushdns`</br> - On Linux (if `systemd` is being used) run: `sudo resolvectl flush-caches` |
