Gemini Code Assist not working with IntelliJ using Dev Container

I am using the latest Gemini Code Assist Plugin for IntelliIJ 1.28.0-243 on a Dev Container. I installed the same on the host, not the client, although it does not work on either host or client. I see the Gemini Code Assist window pane in the IDE but there is no content in the pane. The same plugin works fine within an IntelliJ instance not running on a virtual machine.

IntelliJ version IntelliJ IDEA 2024.3.5
