I have a Power BI Gateway installed on one the servers at the office and it helps to sync data into the designated workspaces in the Power BI Cloud. This has been up and running since Oct 2017.
For the past few days, I have noticed that the Power BI Gateway is systematically offline for my first sync at 2 AM UTC but runs perfectly well for the next sync at 2:30 AM UTC. When I launch the sync manually afterwards, it runs without any issue. I honestly don't know where to start looking for the problem.
