    Hi there, 

    Welcome to the Box Community! 

    If you are having trouble uploading files or folders, please try the following troubleshooting steps:

    • Please ensure your web browser is the latest version of ChromeFirefoxSafari, or Edge
    • Try clearing your browser's cache. If this does not resolve your issue, please proceed to the next step.
    • Verify that you are using one of our recommended operating systems.
    • Verify that the file's name is valid. Box only supports file or folder names that are 255 characters or less. File names containing non-printable ascii, "/" or "\", names with leading or trailing spaces, and the special names “.” and “..” are also unsupported. Box supports only Unicode Basic Multilingual Plane (BMP) characters in file and folder names.
    • Verify that the file or folder's path on Windows machines is under the 255-character Windows limitation. Folder paths that exceed 255 characters may truncate the content's name before uploading to Box.
    • Make sure you are uploading files smaller than the maximum for your account type. To determine your maximum, click on your initials in the top-right corner of the page and select Account Settings. Then, click on Account and your Max file size will be listed under Account Details.
    • Try uploading using the File upload method instead of Folder upload, or vice versa.
    • Check your network connection to Box. If connected to the internet with a wireless card, check to see if the connection to the internet drops intermittently. If this is the case, we recommend the Folder upload method.
    • Try temporarily disabling or configuring your firewall to allow Box as a trusted site. You may find that your anti-virus software includes a built-in firewall. If you are attempting to access Box from an office setting and experience upload issues, then please contact your IT administrator or internal Help Desk.
    • Proxy servers may sometimes cause failed uploads. If you see the error message: An error occurred with the upload. Please refresh the page and try again. Please contact your IT department or Help Desk and ask them to check your proxy configuration.

    Thanks!

    I had the same issue and went through all of the steps above (excepting the firewall configuration) and still had the issue. I wanted to remark that I am using MacOS Sonoma 14.6.1 and I use Office365 OneDrive for Cloud storage. I resolved the issue by moving files that I had not stored locally from OneDrive to storing the files locally. Everything works well now.
