Hello,
I've managed to install and configure a data gateway in an environment I'm using to get started with Power Automate Desktop:
The data gateway is up and running as I can see in the Power Platform Administrator, but when trying to add an action to a flow I always get the message:
There's an issue with your credentials. Check your credentials or use different credentials to connect to the gateway.

Why is this? Is there a trick or what can be wrong here??
