On-Premise Gateway: not a valid connector

I have set up a gateway to my on-premise sharepoint data.

PowerApps shows my connection working under the "connections" tab (see attached image).

I have created 2 connections through the gateway, one of which works and one that returns the error:

"An error occurred on the server. Server Response: Not a valid connector Error response." (attached image)

All threads I found about this error contain more information in form of a JSON message, this doesnt show up for me.

The gateway must work fine because of the other working connection.

I cannot figure out how these Lists behave differently, even though they are from the same Site.

Hi @Jannis 


Could you please remove the connection and connect it again?

Do you try to uninstall and reinstall your gateway to test?


Best Regards.
