A couple years ago I movd WHMCS instance to LE. 90 days later the cert lapses because it wasn't renewed. So I punch in, re-issue, everything is fine. For 90 days.
That repeated for like a year, when I finally gave up and spent a 15 minutes (compared to 3 for the manual re-issue) to dig up and fixed the reason the auto renew didn't work. It work fine ever since.
