What's Wrong?

JetBrains IDE plugin integration does not work when Claude Code runs in Docker container, Claude Code is unable to connect to the IDE. I have tried the "Accept connections from all network interfaces" setting.

This is on Linux, and I am running the Docker container with docker run --network=host ....

What Should Happen?

It should be able to connect to the IDE.

@mikaelstaldal - is your IDE running locally or in the container? Using IntelliJ in remote development mode (Devcontainer) works for me, as long as the Claude Code plugin is installed on the host, not on the client, and Claude code is also installed and running in the container.

The IDE is running locally.
