What does HRESULT 0x8029020B (TBSIMP_E_COMMAND_CANCELED) mean?

TBSIMP_E_COMMAND_CANCELED

The submitted TBS command was canceled

TBSIMP_E_COMMAND_CANCELED (0x8029020B) means the request did not complete normally because cancellation was requested or propagated through the implementation. It should not be rewritten as an unknown TPM error.

Evidence to capture

Record cancellation source/token, command ordinal, queue/scheduler state, timestamps, caller timeout, and whether a TPM response was ever received.

Focused correction

If cancellation was intentional, handle it as such. If a timeout triggers unwanted cancellation, correct the timeout/ownership policy before retrying and ensure retries are safe for the command.
