HTTP challenge
To obtain a certificate from the ACME service, their servers verify that you have control over the domain for which the certificate will be issued. This validation process is automated through anynode.
anynode must be reachable via port 80, but it will only listen on that port during the certification issuance process when necessary. Therefore, port 80 needs to be opened in the firewall as well.
Please choose the interface/IP address that should be utilized to address the challenges.
