Is it possible to renew certs from letsencrypt with just the private key and fullchain file?
If not, can one just remove all the letsencrypt files and .well-known directory and apply for new certification using certbot or other programs? Or would I need to wait for the current cert to expire?
A small company approached me with this issue of not being able to renew their certs. I found everything to be a mess to where I'm not sure how it was done in the past.
