PowerBI Service refresh failed (more than 120 minutes to refresh)

Hi all,

I have a few pbix files that take 20 minutes to refresh in the PowerBI Desktop.

Those same reports fail to refresh (automated) in the PowerBI Service due to a connection time-out (more than 120 minutes).

I gave it a few days but it is already 5 days in a row now.

The pbix files are between 140 and 200 MB.

What can be the issue?

Thanks in advance,

Kind regards,

Yanni
