We tried to update the SSL cert via letsencrypt today and ran into trouble.
Since this is the first time we have renewed a cert this way, we had trouble understanding the commands.
Anyway, we ended up blocking us from doing the renewal for about a week.
Which means the cert on the site will be broken for about a week.
See this post for an explanation: https://community.letsencrypt.org/t/how-can-i-completely-reinstall-lets-encr...
Sorry for the trouble,
Mark.
