205 is NNTP for "closing connection - goodbye!"

So that mean that the server actually closes the connection (at least
from Gnus' point of view).

FIN means that the sender (which in this case is the client machine) has
no more data, and RST is reset the connection.

If the time stamps of the packages, and the order in wireshark can be
trusted, then for some reason, the TCP connection is torn down from the
client side, and the NNTP server responds to the terminating TCP
connection with a 250 response... which of course makes Gnus thinks the
server has closed the connection.

But where the FIN and RST comes from, I have no idea.
