On-Premise Data Gateway: Data source access error


I installed On-Premise Gateway on a standalone Windows 10 machine with local SQL Server 2016 including Analysis services running.

Installation and Setup is fine. Under PowerBI Desktop I built a report on "Analysis Services" as data source - running perfectly.

In my PowerBI account, under "Settings" - "Manage Gateways" I added this as data source which results in "Connection Successful".

I also called "Map user names" where I replaced <My PowerBI UPN> --> <My local SSAS Admin> (format: MyMachine\MyUserName).

But running the report results in the error: "There was a data source access error. Please contact the gateway administrator" and under details: "Couldn't load the schema for the database model".

I tried to restart the gateway service but failed:

""EnterpriseGatewayConfigurator.exe Error: 0 : Exception: Microsoft.PowerBI.DataMovement.GatewayCommon.RestartGatewayException: Fehler beim Beenden/Starten des Gatewaydiensts. ---> System.InvalidOperationException: Der Dienst On-premises data gateway-Dienst wurde nicht auf dem Computer . gefunden. ---> System.ComponentModel.Win32Exception: Der angegebene Dienst ist kein installierter Dienst"

My taskmanager shows, that the service is running and healthy:

PBIEgwService   23940   On-premises data gateway service    Wird ausgeführt

Is it possible that there is a localization issue? On my machine I have german OS but decided to install PowerBI in english. So I have running the service On-premises data gateway service but EnterpriseGatewayConfigurator expects On-premises data gateway-Dienst


2 issues:

- Can't (re-)start the service because it is apparently not running

- Can't access my report from within PowerBI Service althoug gateway connection is successfull.

Please restart your machine to see if you can start/stop the service.


If the issue still persists, please capture the Fidder trace and open SQL Profiler on SSAS instance to see detail error message.

Re: On-Premise Data Gateway: Data source access error

Hi Simon,

thanks for your reply and your recommendations.

As I already mentioned, the gateway service is installed and running. I can start/stop it. Nevertheless, the "On-premises data gateway" utility states that the service could not be found and I also can not restart the service from within the utility. I am pretty sure that this is a localization issue. The utility always looks for "On-premises data gateway-Dienst" (german word for service) but installed is "On-premises data gateway service".

I'll try to uninstall the product and then run again PowerBIGatewayInstaller.exe. I could not find this installer for a specific language. I suppose that this one version uses the language of OS which in my case is German. All dialogs are in German. I found no way to make this installer use english language. 

In order to confirm my suspicion I'll try to repeat this procedure on a VM with english OS.

Re: On-Premise Data Gateway: Data source access error



same issue here!

Workaround: rename the service to: "On-premises data gateway Dienst", restart the Server

and it's working.
