What does HRESULT 0x80632081 (PEER_E_INVALID_CREDENTIAL_INFO) mean?

PEER_E_INVALID_CREDENTIAL_INFO

Where the peer stack rejects the operation

PEER_E_INVALID_CREDENTIAL_INFO — HRESULT 0x80632081 marks the PEER_CREDENTIAL_INFO supplied for membership issuance contains invalid role, lifetime or identity data. Treat it as a group membership result rather than a generic peer-networking failure.

Evidence to preserve before retrying

• Record the first failing surface among PeerGroupIssueCredentials and PEER_CREDENTIAL_INFO.
• Preserve credential structure fields, issuer identity, subject identity, roles, validity interval, flags and existing GMC chain.
• Place successful creation or discovery, state-changing events and the failing call on one timeline.
• Keep peer names, identities, record identifiers, invitation data and endpoints in their original Unicode or binary representation.

Controlled isolation

Issue credentials using the existing member information or a minimal documented credential structure, then add optional fields individually. Change one variable only; simultaneous changes to identity, cloud, database and firewall state destroy attribution.

Neighboring result

PEER_E_INVALID_CREDENTIAL differs because credential-info rejects the issuance input structure; invalid-credential rejects a credential or invitation used to join. Keep both HRESULT values in chronological order because a corrected prerequisite can expose the next validation stage.

Safe response

Repair the credential-info structure and verify issuer authority before generating a new invitation or GMC. Preserve durable graph databases, group exports, identity certificates and invitation artifacts before changing them.
