What's Wrong?

Summary

/remote-control in the Claude macOS desktop app returns "Remote Control failed to connect: /login" on a Max plan with no API key override. Local sessions started on desktop never appear in the iOS Claude app's Code tab. Sessions started on iOS do appear on desktop — the failure is one-directional, consistent with the desktop-side bridge never registering with the Remote Control service.

Reproduction

1. Sign in to Claude macOS desktop app on a Max plan (latest version).
2. Settings → Claude Code → enable "Enable remote control by default".
3. Start a new Code session on the desktop.
4. Type /remote-control in the session.
5. Observe: Remote Control failed to connect: /login.
6. Open the iOS Claude app, pull-to-refresh the Code tab. The desktop session is not listed.

Expected

Desktop-started session appears in the iOS Code tab and can be driven remotely.

Logs

From ~/Library/Logs/Claude/main.log, every enable attempt produces:

\``
[info] Enabling remote control for session local_<uuid>
[info] [remote-control] bridge_state: failed — /login
[error] Failed to toggle remote control for local_<uuid>: /login
\``

This reproduces across many sessions over multiple hours.

Notably, the same log shows OAuth itself is healthy in the same time window:

\``
[info] claude.ai account active and logged in
[info] [oauth] using cached token for orgId=<orgId>
\``

The cached OAuth token's scopes are user:inference user:file_upload user:profile. My speculation (from outside the system) is that the Remote Control bridge requires a scope not present on the cached token, which would explain why the bridge gets a /login redirect despite the rest of the app being authenticated, and why signing out and back in didn't help — the OAuth flow may not be requesting the needed scope.

Tried

• Signed out of all devices and signed back in.
• Toggled "Enable remote control by default" off, full Cmd-Q quit, relaunched, toggled back on.
• Confirmed ANTHROPIC_API_KEY is unset (only reference in shell config is a commented-out line).
• Confirmed no CLAUDE_CODE_USE_BEDROCK/VERTEX/FOUNDRY overrides.
• Confirmed running latest desktop app version (in-app update check returned "You are running the latest version").

Environment

• Claude desktop app 1.9255.2 (per Sentry baggage in process env)
• macOS
• Max plan
• No API key configured
