Installation fails when installing manually

Problem

Git Integration for Jira application installation fails when using the file upload install method.

Diagnosis

• 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.

Cause

The Jira system is behind a type of proxy, firewall or network security and the network security/proxy has a limitation on request size.

Solutions

See the following articles from Atlassian on a resolution:

• Updating add-ons by file upload hangs using UPM

• Attaching a File Results in Request Entity Too Large
