Summary
When attempting to install or update a Jira Software or Service Management license, it can stall with the message 'Updating license key', and the progress bar spins from side to side as shown in the screenshot:
Environment
Any Jira version.
Cause
The HTTP POST request to the URL /rest/plugins/applications/1.0/installed/jira-software/license, made in order to update the license, is being blocked by a reverse proxy, firewall, or other network equipment.
Solution
Ensure HTTP POST requests to the endpoint /rest/plugins/applications/1.0/installed/jira-software/license are not being blocked.
It is also possible to use the private REST API endpoint to update the license:
