Unable to install demo version of jira-oauth-1.2.17.jar

I downloaded the plugin jira-oauth-1.2.17.jar but when I navigate to JIRA Server 8.13.20's  Manage Apps page (in System) and try to upload, it says "Installing jira-oauth-1.2.17.jar..." but then freezes.    I notice that my laptop's fans startup noisly for several minutes.  The JIRA server is on a remote host that is disconnected from the Internet. In atlassian-jira.log, I see:

We figured it out. I copied the file to an HTTP server residing near the JIRA server and uploaded from that URL (instead of from my laptop’s hard disk), and that fixed it.

Hi @Covance Genomics Lab System Support,

There could be a few reasons for this issue. However, the most common reasons are:

  1. It could have occurred due to the admin session timeout in Jira - in this case, try to re-install the plugin after refreshing the browser page.
  2. This could be due to proxy. Do you have any reverse proxy set up for Jira server like Nginx? Generally, Nginx has max upload size set to 1 MB due to which plugin upload doesn’t work.
    If this is the case, you can solve it by increasing client_max_body_size directive in Nginx and make sure it’s atleast 6 MB (size of the plugin).

P.S - I work for miniOrange, I would suggest you reach out to us at so that we can assist you in a better way.

Best Regards,
