Hi
We have been having the following problem on our jira installation:
When uploading attachments to some issues, an internal error shows up.
Following some of the questions I found online, I created a HAR of the issue and was able to reveal that the POST data was incomplete and the server response code was "0". The size of the body also was 0 bytes.
Further than that, I don't know how to find out more about this issue or how to even attempt to solve it.
