Explanation

ACME (Automated Certificate Management Environment) certificate configuration on Expressways must be done on the Expressway-E. This is because the Expressway-E is the internet-facing node with a publicly resolvable FQDN and IP address, which is required for ACME Certificate Authorities (such as Let's Encrypt) to perform domain validation challenges (HTTP-01 or DNS-01). The Expressway-C is an internal node and cannot be validated by public CAs via ACME. The ACME automated renewal setting is also configured on the Expressway-E to maintain certificate validity.
