I have not seen any other reports of this problem. I think it would be best if we could create a support case about this problem and if you could then provide some details of the Jira issues/attachments in that support case. Perhaps this can help our Cloud support team to troubleshoot this issue further.
You can create a support case by going to
This will ensure that your issue is reported to the proper Cloud support team that can better investigate this problem.
The problem never occurred again for me, so it was hard to trouble shoot.
My best guess is that I didn't wait long enough for the file to upload before I added it to the ticket. Suggestion: when you first attach a file to a ticket, wait to be sure it has completely uploaded (a little check mark appears) before you actually insert the file.
Hope this works for you as well.
Yes, the same happens to me. We are on Cloud ServiceDesk Jira version and it happens infrequently. There is no rhyme nor reason. I wait until I am sure it has uploaded, then save and ensure it still there. Next day or so, it says Failed upload / Retry and simply has lost the attachment. When changing to the old view you can at least see the name of the file that you uploaded but it is not in the attachment list. On the same service request, later attachment stay - go figure. I have raised a service request with the Jira Helpdesk. Will see what they come back with.
Same to me yesterday: 2021.07.13. I uploaded a file and today it's not there. I'm using JIRA Cloud as well. The weird thing is I looked through the ticket history and it shows the file was actually linked with the standard JIRA attachment link syntax e.g. "[^ fileName.doc]", it's just that this morning the file vanished into the ether... I had to reupload it. I know you all had an outage yesterday with Bitbucket and I wonder did it also affect jira???
