If your JIRA and Git servers are running through a firewall, configure the firewall to allow access using the URL schemes for git repositories. For authentication issues, make sure to check first the correct port for its connection.

Below are the default ports for common git URL protocols:

Default port
port 22
port 9418
port 80
port 443

Test git connection and repository URL by doing the following:

  1. Install git client (or run sudo apt-get install git)
  2. Place your ssh key into ~/.ssh
  3. Clone the repository (or run git clone <your_repository_url>)

Information: The Git Integration for JIRA will run successfully if the above connection test ran without errors.
