I think this error is valid as that's what actually happened. Perhaps
it could be caught and a nicer error message be displayed though, I'll
repeat it at home and see how it can be done...

After this, the server is flag as "denied" in the server buffer (press
`^' in the group buffer) which is why nothing seem to work any
more. When you've reconnected, you can press `R' in the server buffer
the reset deniededness of servers, and things should work again and
you shouldn't have to exit and restart Gnus.
