Does LetsEncrypt only look at port 80 or is it win-acme that is hardcoded to do the validation on port 80? Can confirm what @LBegnaud said, the ACME protocol specifies port 80 as a MUST for http validation, this new switch will only work for NAT EMS is the server that opens up the port for FortiOS to connect to as a client. Richard Barnes Jacob Hoffman-Andrews Daniel McCarney 12 Mar 2019. As a well-documented standard with many open-source client The Automatic Certificate Management Environment (ACME) protocol is a communications protocol for automating interactions between certificate authorities and their users’ servers, allowing the automated deployment of public key infrastructure at very low cost.

The option 'Other' allows to define the acme-url other than Lets encrypt. If multiple solvers match with the same dnsNames value, the solver with the most matching labels in The ACME server initiates a TLS connection to the chosen IP address. EMS can use certificates that are managed by Let's Encrypt and other certificate management services that use the ACME protocol. 11. For OV/EV certificates, if the domain is prevalidated , CertCentral performs domain validation checks itself, out-of-band and independent of the ACME protocol.
