What's Wrong?
Dispatch on mobile permanently shows "Escritorio sin conexión"
(Desktop offline) even though:

• Desktop app is open and running
• Cowork works normally on the same desktop
• No VPN active
• No firewall blocking Claude

Steps to reproduce:

1. Open Claude mobile app
2. Navigate to Dispatch
3. Observe error: "Escritorio sin conexión"

Expected behavior:
Dispatch connects to the desktop app normally.

What I've tried:

• Fully closed and reopened desktop app
• Logged out and back in on both devices
• Restarted the computer
• Verified no firewall blocking

Platform:

• Desktop OS: Windows [completar versión]
• Mobile OS: Android [o iOS, completar versión]
• Claude Desktop version: [ver en la app → About]
• Plan: Pro / Max [el que tengas]

No specific code needed — this is a connectivity/pairing issue.
Desktop Cowork works fine. Only Dispatch fails.
