We have an issue, which was discussed already a few times: We can't preview nor download attachments in some JIRA tickets. Strangely it works in some tickets, in others it won't.
According to our network provider we need to know the network ports, over which JIRA tries to send the files, so we can perform an SSH exclusion for these ports.
Can someone tell me, on which ports JIRA is doing this? I searched quiet some time here, but I didn't find the answer...
Have a nice day and an even nicer weekend!
