Connecting to on-premise Webcon from Power BI Service

0

I'm trying to connect to Webcon with Power Bi. Service I set up OData user and API key as described here https://community.webcon.com/posts/post/odata-format-in-webcon-bps/346. I do not have a problem to connect using Power Bi desktopapp but after uploading report to Power Bi service there is a problem with refreshing although I set up on-premise gateway on Webcon vm - invalid credentials.
Has anyone tried to connect from Power Bi service to Webcon on premise server?
