Error: 401 Failure to download a successfully restored file from the Clumio Portal


When attempting to download Reports/Restored files, a 401 error can be observed for the file after clicking on the download link. Some users may also observe a zip file downloaded with '0 bytes' of data or showing 'Unauthorized access'. 

Root Cause

The reports/restored files are made available to users through a '' domain as opposed to the '' domain used by the Clumio portal. As a result, the cookies from the Reports/Restored file sites may be treated as a 3rd party site. Some browsers block these sites based on their default settings. To address this behavior, go through the steps mentioned below. 


If you are experiencing a similar issue while downloading Reports/Restored files from the Clumio Portal, validate the following browser settings:

Chrome Browser:

  • Under Settings -> Privacy & Security -> Cookies and other site data -> Allow all cookies


Firefox Browser:

  • Under Settings -> Privacy and Security -> Custom -> Cookies (All Cookies)


Safari Browser:

  • Under Preferences -> Privacy -> Prevent cross-site tracking (Uncheck)


Once changed, please log out and log back in, and try the download again.
