here I received an email regarding my free certificate let’s encrypt 3 months. informing me that ACMEV1 will no longer be usable from June 1, we must switch to ACMEV2
only here it is not me who to install this server, I have solid computer bases but I do not know this system at all apart from stupidly renewing my certificate for the moment that is all.
do you have a procedure to follow?
Thank you very much
