Connection to SharePoint 2016 on-premises


I have set-up an On-Premise Data gateway. That looks like it is working fine and the Network status is Connected.

I have then gone into PowerApps and here I have been able to see the gateway is Live and have made a connection to on-premise SharePoint.


As far as I can tell the connection details are good, but when connecting to either PowerApps or Flow I get errors.


For Flow, I select a template to check for a new item, configure (It does error, but entering a custom value I get the right values entered) and save the flow. On the Flow details and there is a 'Unable to check for new events' error above the Run History and on opening that I see ProxyAuthenticationRequired error against the 'When a new item is created' action.


Am I entering the connection details incorrectly? It only asks for

Authentication Type (only Windows) - also Windows in SharePoint

Username: i entered domain\username of my account which is site coolection admin for the site I want to access

Password: entered correctly

Gateway: as set-up and live


All help gratefully received.
