Attachments cannot be read

[Rich Bean]

We recently updated to 8.21.0 and now all attachments cannot be read. I have verified that uploading them puts them in the correct place and creates the thumbnail for image files, but Jira itself cannot read them aftewards.

I can find nothing helpful in the logs. I have ensured that the application has read/write perms (and verified by uploading a new attachment since updating) and am at a dead end.

Thanks,
