Gateway Administrator Removed

Hi Anonymous,

---

 In your last screenshot, what is the result when you select the online data source to connect to? 

---

When I select the online Gateway, it works fine.

But this one is linked to the test SSAS server (Timesheet-RUAT). I can always create a third Gateway (f.i. Timesheet-Prod) and link it to the Production SSAS server.

But my point is that the first Gateway (without admin) still exists and still shows up in Power BI which could be confusing and annoying for my other colleagues.

---

 When I firstly delete the Administrator from Manage Gateways as shown in your first screenshot,  the administrator is not deleted immediately. The process of deleting Administrator seems to get stuck, I refresh the current webpage and get the notification as follows. 

---

I believe I had the same behaviour.

The service says that I haven't got any data gateway, which is correct according to the permissions. But there still is a gateway without any admin account, so nobody can manage it.

---

 After that, I try to connect to SSAS database from Power BI Service, everything is well. It works even if I create a new gateway and create new data source under the newly registered gateway.

---

Did you create the new gateway on the SSAS server itself by using the On-premise data gateway application? When I use the name "Timesheet", it gives an error: "Gateway Name has been taken".

Gateway name has been taken. Please choose another name.

I've uninstalled the on-premise data gateway and reïnstalled, but same message.

I also tried to "Migrate, restore or takeover an existing gateway", but after typing "Timesheet" in the on-premise data gateway name and the recovery key, it restores Timesheet-RUAT.

How do you delete the administrator from Manage gateway? Do you register the two gateways using same account?

---

I've always used the same account. The admin was removed from the power bi online service: manage gateways - Administrators - select Name - Remove
