If you run certbot certificates it will show your certificate(s) and the domain(s) it covers. If it doesn’t cover both the apex and the www, you can

  1. run certbot again and have it create a cert for both the apex and the www;

If you go with this option, you run certbot certificates to get the name of the cert you want deleted. Run certbot delete (certificate name of the cert you want deleted). You should be left with only your new cert (with both the apex and the www).

or (easiest)

  1. run `certbot --expand -d existing.domain -d added.domain

This will update your cert with a new cert containing the original domain and those you add with the -d flag.
