The AI Dispatch instantly ends every task on one Windows PC host
A Max subscriber uses AI Dispatch from his iPhone: on his daily Windows PC tasks run normally, but on his Windows 11 Pro server PC every dispatched message instantly returns "Task ended" and no task ever starts, even though regular Cowork tasks run fine on that machine. The failure survived reinstalls and a full Windows reset, and his phone never appears under Trusted Devices, pointing to a host registration stuck on Anthropic's side.
How it works
- Sent Dispatch messages from iPhone to the server PC host, Each message showed as Read but immediately returned "Task ended", Reinstalled apps, cleared data, re-paired devices and reset Windows entirely, Failure persisted unchanged; escalated to Anthropic support
Why it’s worth knowing
The breakage is tied to the machine's identity, not its software: a factory-reset PC with a fresh install fails identically, while the same account works on another PC.
