Summary

Users are unable to install any apps to Jira Cloud.

Jira was recently restored from a backup or imported from a backup to cloud.

You might encounter an error message indicating a missing default group for Jira Software. For example this error message in your browser's developer tools:

 msg:	 Failed to create Connect user remotely: {"schemas":["urn:ietf:params:scim:api:messages:2.0:Error"],"status":"404","detail":"No default group for Jira Software","errorType":"NoDefaultGroup","message":"No default group for Jira Software","data":"Jira Software"}	
    	 
stack:	 com.atlassian.plugin.connect.api.lifecycle.ConnectAddonInstallException: Failed to create Connect user remotely: {"schemas":["urn:ietf:params:scim:api:messages:2.0:Error"],"status":"404","detail":"No default group for Jira Software","errorType":"NoDefaultGroup","message":"No default group for Jira Software","data":"Jira Software"}
...

Backup restore or import from server has displaced default application group

Restoring  an instance from a backup might displace the default application access group. When that happens, apps can't identify the default group required for installation. 

1. Go to the Admin Management section https://admin.atlassian.com

2. Select Product Access 
3. Click on Review Imported Groups in the highlighted section
   
4. Select Approve for all Groups

Cloud subscription has expired

If you haven't recently restored from backup or imported to Cloud, the issue may be because your Cloud subscription has expired.

When attempting to install an app, the app validates if the Instance has a valid license. If your subscription is expired, installing any app becomes impossible.

Renew your subscription to fix the problem if it has expired. You can tell if your subscription has expired by checking your Billing cycle.

1. Navigate to your Admin Management section  https://admin.atlassian.com
2. Select Billing  > Manage Subscription and check if your subscription is expired
3. Update payment details and/or renew your subscription as necessary
