[BUG] Dispatch pairing permanently failing — Windows 11 Pro 25H2

[levanrami]

Preflight Checklist

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

What's Wrong?

Dispatch has never successfully paired on this device. Every attempt results in "Pairing failed" on the mobile app. No connection has ever been established. This has persisted for several weeks across multiple attempts.

What Should Happen?

Mobile app should pair successfully with Claude Desktop for Dispatch sessions.

Error Messages/Logs

No error log visible — mobile app shows "Pairing failed". No further detail displayed.

Steps to Reproduce

1. Open Claude Desktop on Windows 11, navigate to Cowork → Dispatch
2. Click to initiate pairing
3. Attempt to pair with Claude mobile app
4. Mobile app shows "Pairing failed" — no connection established
5. Repeatable every attempt, for several weeks

Additional Information

• OS: Windows 11 Pro, Version 25H2, Build 26200.8328
• Claude Desktop version: [Help → About]
• Claude mobile app: [version + iOS or Android]
• Hardware: Intel Core i7-14650HX, 32GB RAM, RTX 4060 Laptop GPU

Troubleshooting already attempted: same Wi-Fi network, VPN disabled,
sign out/in both devices (desktop first), Dispatch toggle off → Ctrl+R
→ on, deleted bridge-state.json, firewall disabled. None resolved it.

Related issues: #45937, #41525 (macOS-specific — this may be a
distinct Windows failure mode, currently underreported).

Experiencing the same issue on Windows 11. Pairing fails every attempt with no successful connection established. Already confirmed same Wi-Fi network, VPN disabled, same account on both devices, Claude Desktop open and up to date, firewall disabled during attempts. Restarted both devices fully — still no luck. This has never successfully paired on my setup. Hoping for a fix soon.

Same issue on Windows 11 Pro, Build 26200 (25H2).

Dispatch pairing fails identically — mobile app shows "Pairing failed"
with no logs surfacing in Claude Desktop.

Tried all workarounds listed in the original report:

• Same Wi-Fi network on both devices
• VPN disabled
• Signed out/in on both devices (desktop first)
• Dispatch toggle off → Ctrl+R → on
• Deleted bridge-state.json
• Windows Firewall disabled

No change. Issue is reproducible 100% of the time on this build.

+1 — would appreciate any update on root cause investigation.
