What's Wrong?
Linking a Cowork task to this computer fails on every attempt with "This task can't be linked to this computer right now." Cowork tasks and connectors work normally on the same desktop at the same time. The failure is isolated to the task-to-computer pairing channel, not general connectivity.
Environment
Platform: macOS
Claude Desktop: latest version (add exact version string from Help > About)
Plan: Pro Max (20x)
Troubleshooting already attempted (none resolved it)
Full Cmd+Q restart and relaunch
Updated to latest desktop build
Computer-use toggle confirmed ON
Clean reinstall from claude.com/download
Signed out both devices, deleted bridge-state.json, re-logged in desktop first then mobile
Confirmed no VPN, firewall, or DNS filtering in the path
Network verification
curl -sS -o /dev/null -w "%{http_code}\n" https://bridge.claudeusercontent.com returns HTTP 426 (Upgrade Required), i.e. the bridge endpoint is reachable and responding normally. Network path to the pairing bridge is confirmed open.
Assessment
All client-side causes are exhausted and the bridge is reachable, which points to a server-side pairing/relay issue rather than local misconfiguration. This matches the known issue class in #45937, #46391, and #67303, where Cowork runs fine but the pairing state is stuck server-side and no local troubleshooting resolves it. Resolution in those cases was Anthropic force-resetting the pairing state server-side.
What Should Happen?
Expected: Task links to the computer and computer use becomes available.
Actual: Same error on every attempt.

Steps to Reproduce
Steps to reproduce
Open Claude Desktop on macOS, signed into a Pro Max (20x) account.
Go to Cowork and open (or create) a task.
Attempt to link the task to this computer.
Observe the error: "This task can't be linked to this computer right now."
Retry after restart, reinstall, and bridge-state reset. Same error every time.
Does this reproduce consistently? Yes, every attempt.
Did it work in a previous version? [answer yes or no. If it worked before and broke, say roughly when. If it has never linked on this machine, say "No, has never successfully linked."]
Claude Model
None
Is this a regression?
Yes, this worked in a previous version
