On my On Premise Jira Software Data Center instance, the atlassian marketplace is not reachable because of internet connection so, I am not getting options to install JSD Data center from there.
In this case, I need to upload JSD Data Center using "Upload an Application" option and I want to upload JSD Data Center version 3.15.1 but I am getting only the latest version 3.15.3 to be downloaded from Atlassian site.
How can I get JSD Data Center version 3.15.1 to upload?
