Workbook export fails in RPAS/Fusion Client 16.0.3.150

Hi all,

We have been facing the following issue when trying to export workbook values in text files:

After a Measure Analysis workbook is built, we try to export it via File -> Export functionality.
The specific selections in the popup window are:
Export to: Text

Export Format Type: Raw Data

An error window appears, as shown in the screenshot below, however, the export finishes successfully after some time around 18 minutes and if the user clicks OK, they can continue their work in the same session.

An additional error message appearing is "A connection to the server has failed (status=504)", however after closing the popup the session is active.
