- Jira admins will see the installation screen in the Universal Plugin Manager (UPM) a message similar to the one below when installing the Git Integration for Jira app via the file upload method.
- The "Installing" dialog hangs indefinitely.
- The error message: "An unexpected error occurred. Refer to the logs for more information." is shown behind the dialog.
The Jira system is behind a type of proxy, firewall or network security and the network security/proxy has a limitation on request size.
