Help
1

Hello,

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.

CertbotACMEClient / 0.9.3 (Debian GNU / Linux 8 (jessie)) Authenticator / webroot Installer / None
Hostname (s): “mail.TOTO.com”, “smtp.TOT.com”, “webmail.TOTO.com”

do you have a procedure to follow?

Thank you very much

Hi @glariture

I don’t know the client you use.

Check, if there is a config file with acme-v01.api.letsencrypt.org. Or a log with that address.

Then check the documentation of that tool how to update to acme-v02.api.letsencrypt.org.

Or check, if there is a newer version required.

So I have to type this command on my linux command line if I understand correctly?

Please start with some basics:

Then check your client documentation.

Or switch to another client.
