Hi ​@AGoe, welcome to the Box Community!

Could you please confirm whether you own the files or if they are owned by someone you’re collaborating with? If it’s the latter, we recommend reaching out to the content owner to have them check their account status, shared link settings, and collaborator permission levels.

If these files were uploaded to your ‘own’ account and you haven’t made any recent changes to the settings, I suggest trying the following troubleshooting steps, which often resolve common access issues:

• Ensure your browser is updated to the latest version.

• Clear your browser’s cache.

• Try accessing Box using a different browser, computer, or network.

• Temporarily disable any internet security or firewall programs to check for potential conflicts with Box. (Note: You may need assistance from your organization’s IT department or helpdesk for this.)

• Temporarily disable any browser plugins or extensions.

Looking forward to getting this resolved for you!

Thank you
Yes indeed i am owner of the files.
It did not resolve the problem.
I am a teacher and I use Box to exchange learning material with my students. They cannot acces any files anymore either. Pretty annoying during this exam period.

And … all of a sudden acces is granted again :-)
Problem solved so far, but I do not know the reason

Hello ​@AGoe, thank you for bringing this to our attention.

At the time, there were no reported incidents that would have impacted file access. For future reference, you may check our Box Status page for real-time updates. While we weren’t able to identify the exact root cause, I’m glad to hear the issue has been resolved and that you and your students are now able to access your files.

Please continue to monitor the situation, and don’t hesitate to reach out if you experience any further issues or have any questions—we’re here to help.

Have a great day ahead!
