Connection issue with embeded reports

[MikeBar]

Hello, 

We are using embedded PBI report to our website.
Usually it works fine, but for a new dataset and report we are gettting a connection error.
In PBI Service the report looks fine, but the embeded report is showing an error with the connction.

I hope you can point me to a solution

503 means the server is present but unable to serve the request (ie it is borked) Raise a ticket with Microsoft if you have a Pro license. Wait for them to fix it if not.
