Power BI Dataflow Error: DataSource.Error: The underlying connection was closed:

[TheMacDaddy76]

Hi there,

We have a dataflow accessing a Business Central Finance datasource and another dataflow pulling in Azure SQL Server data as well.  Both of these now have refresh issues where they come up with the following error:

  Error: DataSource.Error: The underlying connection was closed: An unexpected error occurred on a send. Request ID: 

with a GUID on the end.

Both of these dataflows were working three days ago.  

We do not have premium capacity.

Regards,

TMD.

A number of users within our business are also experiencing refresh errors on dataflows. Seems to be intermitant as the refresh is successful on occassion, but the issue does appear to be systemic. We are connecting to various sources such as SharePoint and Common Data Service.

Thanks @jaywalkar, is this a recent experience?  Ours only kicked off on the 14th of Jan!

Yep, looks to have started around the 12th Jan for me.

Hi @TheMacDaddy76 

So far, your problems still exist, right ? In addition to the refresh issue you mentioned, are there any other issues with Dataflow? For example, can't open, can't edit?
