Hey there,

Do you have any idea why some of the old attachments are broken? like the picture below:

any comment could be useful.

Hi @Mohammad RahmaniNasab Does the attachment preview is not working or whole attachment is broken and not showing the expected results?

Also, is there is any recent migration happen for the attachment directory on the Confluence shared home?

[Mohammad RahmaniNasab]

It doesn't exist even on the server folder. and this server has no linked confluence shared

I should mention it's kinda old, attached about 2 years ago

Hey there Mohammad,

The first question that comes to my mind is whether or not a major Jira upgrade took place recently on your instance. If yes, it might be good idea to take a look at the relevant migration guides as they will inform you on naming-scheme / structural changes that must be catered to in order to have your data behave "normally".

That aside, the most common reason for broken attachments is usually the fact that they no longer exist. Ensure that the files you are looking for are present in the server's corresponding home directory. If not, with luck, some of your backups may still have the files in question available.

Best regards,
Zuri S.

unfortunately the corresponding directory doesn't have missed files, although other files of this issue are present and have no problem opening them.
