I have AWS EKS behind AWS Load Balancer
Lets Encrypt doesn't work at all with AWS NLB, and by using AWS Classic Load Balancer, i am able to register ONLY one host, after that for every other host i am getting the error ACME 403 Unauthenticated
this same error i am getting also when i use AWS NLB
error:

obtaining tlsSecret "test1.mydomain.com"."ambassador"
    (hostnames=["test1.mydomain.com"]): acme: Error -> One or more domains had
    a problem:

    [test1.mydomain.com] acme: error: 403 ::

EKS 1.21 (newly created - Edge Stack is the first resource)

I have the same issue with GCP. Even the first host fails some times

Hi there,

This is a known issue that will be solved in a future release. Currently when there are no Host objects present, Edge-Stack uses a synthetic host with a self-signed certificate so that it can respond to requests. After you create your first Host, this synthetic Host goes away. Without a wildcard host to respond to the ACME challenge then all Hosts making use of ACME will fail after the first one is created.

Unfortunately this information was not more visible in our documentation. We've added information about this issue and workaround to all of the ACME documents now until it is resolved in a release.

You can follow this document to quickly get started with your own wildcard host and self-signed certificate.

Thanks for bringing this to our attention and please let us know if you have any other issues getting started with this.

Thank you for your help @AliceProxy. However, I still can't use ACME cert management...
I've applied a Listener, a wildcard host and then tried to generate the host with ACME. The error changed, but it still didn't complete... Below are the configuration files I used. tls-cert is a secret created as demonstrated in the link you've sent.

apiVersion: getambassador.io/v3alpha1
kind: Listener
metadata:
  name: edge-stack-listener-8443
  namespace: ambassador
spec:
  port: 8443
  protocol: HTTPS
  securityModel: XFP
  hostBinding:
    namespace:
      from: ALL
---
apiVersion: getambassador.io/v3alpha1
kind: Host
metadata:
  name: wildcard-host
spec:
  hostname: "*"
  acmeProvider:
    authority: none
  tlsSecret:
    name: tls-cert

apiVersion: getambassador.io/v3alpha1
kind: Host
metadata:
  name: grafana-host
spec:
  hostname: "mylink.example" # Just replaced to post
  acmeProvider:
    email: "myemail@email.com"

These are the events in kubectl describe grafana-host
