"The Qlik Gateway was installed on SQL Server 2017 Windows Server 2016, and it was working well, but it started giving me the following error: Status(StatusCode="Internal", Detail="Error executing command:. connectiontest: ConnectorServiceLookupError(1101 - error retrieving node to service the command: mssql: Error: No node supports data source mssql (registered datasources: 1)) (DirectAccess-2507)"). It has already been uninstalled, reinstalled, and the gateway was updated to a new version, but the error still persists. The service was stopped and restarted, but still nothing. Do you have any idea what it could be?"
