- [x] I am using the latest version of Claude Code

### What's Wrong?

I just upgraded to v2.110.0 and immediately noticed I could not reactivate Remote Control mode. I had Claude investigate the issue internally and he produced this report below:

Claude Desktop 2.110.0 (Windows), Claude Code CLI auto-updated 2.1.270 → 2.1.271 at 2026-09-16 20:04.
Remote Control connected fine at 17:42 on 2.1.270. Every enable since the first session spawn on
2.1.271 (20:54:50) fails instantly:
[remote-control] bridge_state: "failed" — "Remote Control server rejected the request (HTTP 403)"
Reproduced 10x across re-login and full app relaunch; app reuses the cached OAuth token each time.
Device bridge (bridge.claudeusercontent.com) authenticates normally with the same account.

### What Should Happen?

Remote Control should activate, but will not with repeated 403 errors trying to connect to Remote Control server.

### Error Messages/Logs

```shell

```

### Steps to Reproduce

Upgrade from prior version to 2.110.0
Attempt to activate remote control in Claude Code chat using /Remote-Control command
Get Remote Control server connection failure 403 error

### Claude Model

Opus

### Is this a regression?

Yes, this worked in a previous version

### Last Working Version

_No response_

### Claude Code Version

not sure

### Platform

Anthropic API

### Operating System

Windows

### Terminal/Shell

PowerShell

### Additional Information

_No response_

Start by reproducing the regression on Windows with Claude Code 2.1.271 after upgrading from 2.1.270, using the /Remote-Control command, and inspect the bridge_state 403 response. Done means Remote Control activates successfully with the cached OAuth token after relogin and relaunch, without the Remote Control server rejecting the request.
