Hi,
I still got this error.
Attempting to renew cert (lightyears-comm.com) from /etc/letsencrypt/renewal/lightyears-comm.com.conf produced an unexpected error: urn:acme:error:serverInternal :: The server experienced an internal error :: ACMEv1 is deprecated and you can no longer get certificates from this endpoint. Please use the ACMEv2 endpoint, you may need to update your ACME client software to do so. Visit End of Life Plan for ACMEv1 - #27 by jillian for more information.. Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/lightyears-comm.com/fullchain.pem (failure)
Please help me.
Thanks.
