Multiple Direct Queries not working in power bi reports

Hi Community, 

I just wanted to ask if anyone else is having any issues with their power bi reports that are linked to direct queries.

All my dashboards that are linked to reports with multiple direct queries having been coming up with errors. 

When creating a new report from scratch and adding a second dataset a 404 Error comes up.

Is this a known issue with microsoft or has their been any changes as of last week that could impact this.

Thanks!
