What does HRESULT 0x8028002F (TPM_E_NO_WRAP_TRANSPORT) mean?

TPM_E_NO_WRAP_TRANSPORT

Wrapped transport is not available for this request

TPM_E_NO_WRAP_TRANSPORT (0x8028002F) means the command asks for a TPM 1.2 wrapped transport behavior that the device, command, or active policy does not permit. It is a transport-session capability/policy result, not an NV storage error.

Evidence to capture

Record transport-session type/attributes, command ordinal, wrapped parameters, TPM capabilities, and policy/authorization state. Confirm the command is one that may legally execute inside the requested transport.

Focused correction

Use an allowed transport-session mode or execute the command outside the unsupported wrapped transport while preserving its authorization requirements.
