I received the message “Your Let’s Encrypt client used ACME TLS-SNI-01 domain validation to issue a certificate in the past 60 days.”
How can I check if this issue applies to me or how to fix this?
When checking the renewal config files of a domain I noticed the following line:
standalone_supported_challenges = "tls-sni-01,http-01"
Does this mean that it is falling back to http domain validation?
