Can't setup a Python Datasource in my Gateway

Hello Community,

I'm using a python script as Datasource in my PBI-Report. Local works fine, but I can't establish a connection in my Gatewaycluster. I'm using an "on-premises-gateway" on two machines (Version 3000.82.4).

After an Upload of the Report in the Service, I open the Gatewayconnection and would like to add this connection to the Gatway. But I can't add this. I see this Information: "Adding to the gateway is not possible."

What can I do here???

Best regards

Torsten
