File pbix published but disconnected

Hi all,

it's been happening to me for two weeks that when I publish a pbix file (dataset) to the service i receive a message pointing out that the dataset has been disconnected to the original sources.

I've never seen this message and I don't know what to do. I need to publish the dataset without disconnecting it to the gateway..in this way it will disconnect each time.

Do you know what I can do?
