We’ve recently seen a significant increase in users encountering the error shown below when attempting to download multiple files from Autodesk Forma.

Fortunately, the issue can usually be resolved quickly by clearing your browser’s cookies and cache. Removing this stored browser data refreshes your session and should prevent the error from occurring when downloading multiple files.
Once you have cleared your browser’s cookies and cache, close and reopen your browser before trying the download again.
Autodesk has provided step-by-step instructions for cleaning your browser cashes and cookies across the most commonly used browsers. You can find the guide here: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-clear-browser-cache.html.
Please note that this process will need to be completed on every machine experiencing the issues, as the browser cache and cookies are stored locally on each device. If you continue to experience the error after following these steps, please contact our support team with details of the issue, including the browser you’re using and any screenshots of the error message, so we can investigate further.
