What's Wrong?

Problem

When using /remote-control on Windows, the session connects (green dot visible)
but messages sent from the web interface (claude.ai/code) or iOS app never reach
the CLI. The conversation remains empty and no messages appear.

Debug Evidence

CLI polling shows: "no work" constantly, despite messages being sent from web interface
Messages work fine from the CLI itself (if you type in the terminal)
This is a one-way communication failure: CLI→API works, but API→CLI doesn't

## Environment

• Claude Code v2.1.81
• Windows 11
• Pro plan
• Network: Direct HTTPS to api.anthropic.com:443 (verified working)

What Should Happen?

In browser and/or iOS/Android, i should see the CLI messages. Also, i should be able to do a simple interactions, like "Hi" and get an respons
