The Jira Data Center and Server mobile app throws one of the following errors when attempting to log in, or when using the app:

We're missing something

This app needs Jira 8.3 or later.

If you’re already running Jira 8.3, ask your admin to install or enable the Jira mobile plugins so you can use this app. 

We're missing something

You've been logged out because a required Jira plugin is disabled. Ask your admin to re-enable it.


The Jira Data Center and Server mobile app requires Jira Server or Data Center 8.3 or later, and the following plugin installed in your Jira site: 

  • Mobile plugin for Jira

If this plugin has been disabled in your Jira site, you won't be able to connect to Jira using the mobile app.


To enable the Jira mobile plugins:

  1. Open Jira in your browser 
  2. Go to  > Manage apps > Manage apps.
  3. Choose System plugins in the drop-down, then search for the following plugin:
    • Mobile plugin for Jira
  4. Expand the listing for each plugin and choose Enable.

Users will now be able to connect to your Jira site, using the mobile app. 

Good to know

This issue is sometimes related to missing headers or cookies that are required by the mobile app, especially if you're using a proxy server that might be filtering them out. If you're still having problems with logging in, see Problems with logging in because of missing headers or cookies.

tip/resting Created with Sketch.

Not an admin? Send this page to your Jira administrator and ask them to enable the apps for you.
