PEER_E_NO_CLOUD
What the HRESULT means
PEER_E_NO_CLOUD — HRESULT 0x80631001 marks the requested PNRP cloud name or scope is not present in the local namespace-provider view.
Reconstruct the sequence
- Identify the first call among PNRP Winsock namespace-provider cloud enumeration, registration and resolution that returned the HRESULT.
- Preserve requested cloud name, scope, interface and IPv6 addresses, cloud enumeration result, PNRP startup/service events and network profile.
- Correlate graph, group, PNRP and collaboration events with application cancellation, disconnect, shutdown and sign-out events.
- Run the narrow comparison: enumerate available clouds and repeat resolution with one returned exact cloud name rather than the configured alias.
PNRP is a Winsock namespace provider that resolves peer names to endpoint information inside an IPv6-based cloud. Cloud selection, registration and endpoint enumeration are distinct steps.
Closest alternative diagnosis
PEER_E_CLOUD_NAME_AMBIGUOUS differs because no-cloud finds zero matching clouds; ambiguous-cloud finds more than one cloud with the same scope/name interpretation. The two codes can occur in one workflow, but they do not justify the same remediation.
Correction and proof
Select an existing cloud or correct the interface/scope conditions that create it; DNS changes do not create a PNRP cloud.
