Hello, We don't implement TLS-ALPN-01 for now, but that's something that I want to have on the long term. Next step for our ACME implementation is to simplify the certificate dump on the filesystem. We could probably implement TLS-ALPN-01, but we need to figure out how it could integrate in HAProxy workflow and configuration. It's not easy because it needs to generate a certificate and select it if the alpn was set to "acme-tls/1". But that's doable in a nearby future, don't hesitate to open a ticket to github about it, I know that it was asked in the past as well but it wasn't a priority at the time.
