I have set up letsencrypt certs on three virtual servers. In each case I failed to change the "Months between automatic renewal" setting from "Only renew manually" to some number of months.
I would like these certs to auto renew.
Is there a way to change the configuration for these certs to auto renew without requesting another cert?
What is the optimal/max number of months that can be entered in the "Months between automatic renewal" setting?
Thanks for helping.
