What's Wrong?

Environment

• OS: [e.g. Windows 11 / macOS Sequoia]
• Claude Desktop version: [check Help > About]
• Plan: Max
• Mobile client: Claude iOS/Android app

Bug Description

The main Dispatch conversation shows "Desktop appears offline. Will run when it reconnects."
on the mobile client, even when the desktop app is actively running and Chrome is open.
The issue appeared in conjunction with the platform-wide outage on April 15, 2026.

Steps to Reproduce

1. Open Claude Desktop on PC with Dispatch enabled
2. Open Claude mobile app → Dispatch
3. Mobile shows: "Desktop appears offline. Will run when it reconnects."
4. Desktop itself also shows the same offline message in the Dispatch thread

What I've Already Tried

• Confirmed Chrome is open and claude.ai tab is active
• Confirmed desktop is awake and not sleeping
• Hard refreshed the Dispatch tab

Expected Behavior

Main Dispatch conversation should be reachable from the mobile client when desktop is
awake and Chrome is running.

Actual Behavior

Dispatch main thread permanently shows as offline. This appears to be a server-side
relay/session issue, not a local configuration problem — consistent with the diagnosis
in #45937 and #45962.

Related Issues

• #45962 — Dispatch shows "desktop appears offline" on macOS 1.1617.0 despite app running

What Should Happen?

When the desktop is awake, Chrome is open, and the user is logged in on both devices,
the Dispatch main conversation thread should show as online and be reachable from the
mobile client.
