D.33 253 0xfd BAD STATION NUMBER

Source: NCP Engine

Explanation: The NCP client could not connect with the NCP engine. Incorrect configuration settings caused the invalid session because an attempt was made to use a bad (undefined, unavailable, and so on) station number. This might occur if the server or process crashed while connections were active, and the connection is no longer valid.

Action: Ensure that the user has an authenticated connection to the server.
