DataSource.Error: Web.Contents failed to get....(503): Service Unavailable

I'm using Azure's log analytics to create a PBI M query and return the data to Power BI.

It used to work fine but recently has been erroring out and now I'm getting this error:

DataSource.Error: Web.Contents failed to get contents from 'https://api.loganalytics.io/v1/ ........&prefer=ai.response-thinning%3Dtrue' (503): Service Unavailable

Has anyone else run into this?

I increased the timoue to 10 minutes, but still no use?
