RST

Explanation:

What is RST TCP?

In a stream of packets of a TCP connection, each packet contains a TCP header. Each of these headers contains a bit known as the "reset" (RST) flag ... One common application is the scenario where a computer (computer A) crashes while a TCP connection is in progress.

Why TCP RST is sent?

RST is sent by the side doing the active close because it is the side which sends the last ACK. So if it receives FIN from the side doing the passive close in a wrong state, it sends a RST packet which indicates other side that an error has occured.
