Problem with double cert generated by mistake


By mistake requested a new cert instead of renewing, so I got one with 0001 ext. And that does not work. Now when running letsencrypt with --renew-by-default, the 0001 version gets renewed. What can I do to renew the working cert before it expires? And what happens when it expires, will the 0001 version work then?

Edit: New cert is ok, but not with prefix www. My mistake.
