What's Wrong?

Claude Code login does not work in dev containers in VS Code.

devcontainer.json:

  "features": {
    "ghcr.io/devcontainers/features/node:1": {},
    "ghcr.io/anthropics/devcontainer-features/claude-code:1.0": {}
  },
  
  "mounts": [
    "source=claude-code-config,target=/home/vscode/.claude,type=volume"
  ],

I login successfully and I authorize Claude Code to use my account subscription, but then I get "Failed to retrieve auth status after login" in the Claude Code chat in VS Code.

What Should Happen?

Login should work

Additional Information

I also tried to run claude from VS code terminal and not just from the extension. Login is successful... but then it immediately says that I am not logged in. Same problem if I click the login button in the Claude Code extension. I tried many times.
