What are you trying to publish. A data source or a view?
What version of Tableau Desktop are you using?
I'm using Tableau 10.1.2 and I'm publishing a workbook that contains multiple datasources (between 20 and 30) and multiple dashboards.
Is there anything on the data source side that would prevent you from uploading that to the internet? such as permissions.
Based on that error message, That's my hunch.
Are they all live connections, extracts, or mix?
All datasources are MySQL databases in Amazon RDS. IT department has already whitelisted corresponding ip ranges.
All of them are live connections.
I'm getting rid of ideas
