ACMEClient update


i got this email today telling me to update my ACME client
can u tell me what i have todo to avoid issues in april on next renewall?

i normaly use these commands:

  • /opt/letsencrypt/certbot-auto renew
  • ./letsencrypt-auto certonly --standalone

What do u need to change or update?
My domain is:
My web server: Ubuntu 16


Try to add the flag --preferred-challenges http to the renew call.


the today update did still work, my next renewal will be in april


If you’re using certbot-auto, and aren’t disabling automatic updates, it’s already up-to-date.

What does “sudo /opt/letsencrypt/certbot-auto renew --dry-run” show?

or “grep pref_challs /etc/letsencrypt/renewal/*”?


so the only thing not working anymore will be https renewals? i think i mainly do it by http


grep pref_challs /etc/letsencrypt/renewal/*. = empty
sudo /opt/letsencrypt/certbot-auto renew --dry-run = succesfully renewed


It seems like you’re in good shape and don’t have to do anything else. :slightly_smiling_face:

Did the command you ran really end with a “.”?


grep pref_challs /etc/letsencrypt/renewal/*


thanks, beter be save then sorry :smiley: ill do a dry run 2 weeks before again to be sure
thanks for clearing it up
