DoQ Error Codes, draft-ietf-dprive-dnsoquic, Feb. 28, 2022

 5.3. DoQ Error Codes

The following error codes are defined for use when abruptly terminating streams, aborting reading of streams, or immediately closing connections:

DOQ_NO_ERROR (0x0):
    No error. This is used when the connection or stream needs to be closed, but there is no error to signal.

DOQ_INTERNAL_ERROR (0x1):
    The DoQ implementation encountered an internal error and is incapable of pursuing the transaction or the connection.

DOQ_PROTOCOL_ERROR (0x2):
    The DoQ implementation encountered an protocol error and is forcibly aborting the connection.

DOQ_REQUEST_CANCELLED (0x3):
    A DoQ client uses this to signal that it wants to cancel an outstanding transaction.

DOQ_EXCESSIVE_LOAD (0x4):
    A DoQ implementation uses this to signal when closing a connection due to excessive load.

DOQ_ERROR_RESERVED (0xd098ea5e):
    Alternative error code used for tests.
