Publishing Report Error for Power BI Data Flows

 

I have made a report utilizing data flows from multiple sources and when I am attempting to publish I am receiving the error below. I did have one report ultimately go through successfully once, but I am sure it will have trouble with a daily refresh. I have found some blog posts on similar issues with SharePoint refreshes and dataflows with no real solutions.

 

Please let me know if anyone else has encountered the same issue when utilizing data flows from multiple sources or if there are any suggestions. I have tried VPN adjustments and that doesn't seemed to have a correlation.
