If Confluence is behind a firewall with no internet access, what is the recommended method to install a plugin?

• A. Download the plugin, then upload and install via UPM
• B. Install directly from Atlassian Marketplace
• C. Use remote deployment tool
• D. Ask Cloud support to ship the plugin

Answer: (A)

In air-gapped environments, the server cannot reach Atlassian Marketplace, so the standard approach is to obtain the plugin package on a machine with internet access and install it offline via the Universal Plugin Manager. Download the plugin file from Marketplace on a connected machine, transfer that file to the Confluence server, then in the admin area open Manage Apps and choose to Upload the app, selecting the downloaded file. The plugin will install and become available, though you may need to restart Confluence or apply a license and verify version compatibility and any dependencies. This offline upload method is the practical, supported way when the server has no internet access, whereas direct Marketplace installation isn’t possible without outbound connectivity.
