Attachment file not found - Confluence 6.5.1

[Daniel Pollak]

When trying to download an .xls we get redirected to "Attachment File Not Found" page.

Up to now customers only complained once. The log shows a warning:

 Following the link I was able to retreive the file at the server - when I renamed the latest file in the archive folder to .xls it opened in excel and I could return the file to the users, who of course now wants to know what the problem was and what we are going to do about this.

Does anyone know a reason for this behaviour? Is there a more elegant way to repair this problem than digging through the attachment folder? Is there a known problem?

Hi, Daniel.

Did you make any import or migration recently?

Please see our documentation that will guide you through the solution:

No, not recently.

Thank you for the link, if this keeps being a problem we shall try this. Sadly we have lots of traffic on our confluence so that we would need a downtime to get a consistent backup.

I have the same problem.  Yes i ran the resolve missing attachment script.  ONLY Excel files throw this error now.  I *think* that before I ran the script other files may have as well.   It was able to recover 77 of 80 missing files.
