  • Web Transfer Client, v1.1.1.47 and later

SYMPTOM

WTC gets AJAX error when transferring multiple large files simultaneously (e.g., 4 files of 3GB each), and the uploads fail.

RESOLUTION

Increase the default timeout for upload requests from 1.5 minutes to 4 minutes.

To increase the timeout for upload requests

  1. Open the index.html file in the Web Transfer Client installation folder.
  2. The default location is C:\Program Files (x86)\Globalscape\EFT Server Enterprise\web\public\EFTClient\jument\index.html.

  3. Find the "fileUploadWidgetAjaxTimeout" flag.
  4. Change the value, represented in milliseconds.
  5. (e.g., 1.5 minutes = 90000 milliseconds; 4 minutes = 240000 milliseconds.)

MORE INFORMATION

This error can be caused by a timeout on one or more requests to the server. The timeout can occur when it takes longer than expected to calculate a large file’s CRC value, and when the browser is having difficulty keeping up.
