[BUG] Dispatch permanently “Can’t reach your desktop” — main thread stuck, Cowork works, Windows

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Dispatch on mobile shows “Can’t reach your desktop. Check that your computer is online and desktop app is open.” Desktop app is open, computer online, on wifi. Phone status shows “Asleep.”

On the desktop itself, the main Dispatch thread also does not respond. I typed “test” twice — no reply, though it shows “Read.” So the desktop cannot reach its own Dispatch thread.

Environment: Windows. Pro/Max plan. Both apps latest version.

Already tried, all failed: full computer restart, fully quit and reopened Desktop app, toggled Dispatch off/on with refresh, confirmed online and keep-awake on.

Same class as #45937, #67303, #49545, #44225 — main Dispatch thread stuck server-side, no local fix works.

Request: please force-reset my Dispatch pairing / desktop registration server-side. What client action triggers re-registration?

What Should Happen?

Dispatch should connect to my desktop and show “Online.” Main Dispatch thread should respond from both desktop and mobile.
