Except when certbot fails (silently) for some unknown and different reason every three months, and you have to ssh in anyway to fix it. Out of all the software I run on my tiny hobby VPS (a few web sites, E-mail), certbot requires more babysitting by an order of magnitude. Even more than spamassassin, which gets wedged regularly. I'm not a professional sysadmin, so something is probably configured incorrectly, but certbot's error messages are so cryptic and non-actionable that I've never been able to solve it. So, I have a calendar reminder every three months to log in to the VPS and figure out what went wrong this time...
