Hi there,
Welcome to Box Community and glad to assist!
In order to address this error, please follow the troubleshooting steps:
- Updating your browser to the latest version
- Clearing your browser's cache
- Using Box with an alternate browser, computer, or network.
- Temporarily disabling any internet security/firewall programs to test whether they conflict with Box (Note: you may need clearance or assistance from your organization’s IT department/helpdesk to do this)
- Temporarily disabling any plugins/extensions in your browser
- Removing unwanted extensions, plug-ins, ads, pop-ups & malware:
Hope it helps!
