Communication Problem with Tableau Data Server

Hello Tableau Community,

I've encountered a problem with a Tableau Prep Flow I am trying to run. I've ran the same flow plenty of times previously so I am not sure where the issue is.

The process:

• Upload my Data Source to Tableau Cloud
• Connect to the Data Source using Tableau Prep to clean and output the extract locally

Now, when I try to run the output flow, after a minute or so, I get the following error message:

System error: TableauException: There was a communication problem with Tableau Data Server. Internet communication error: Transferred a partial file (10az.online.tableau.com)

Has anyone else had experience or thoughts about this? Thanks in advance for any help.
