cert-manager is trying to use dns-01 instead of https-01 resolver

Question

I'm trying to issue certificates for my Kubernetes cluster through the cert-manager using the HTTP challenge verification. However, for some reason, the challenge order is trying to use the dns-01 verifier, which is not configures.

I was trying to figure out with different configuration, removing and installing cert-manager again, but nothing helps. It is working from other ACME clients.

I'm using cert-manager v1.2.0.

This is my ClusterIssuer with the http-01 solver:

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: clusterissuer-test-acme
  #namespace: default
spec:
  acme:
    server: https://lab03.test.com:8432/acme/directory
    # Email address used for ACME registration
    email: [email protected]
    # Name of a secret used to store the ACME account private key
    privateKeySecretRef:
      name: issuer-acme-secret
    # Enable HTTP01 validations
    solvers:
    # An empty 'selector' means that this solver matches all domains
    - selector: {}
      http01:
        ingress:
          class: public

This is a certificate I'm trying to issue:

apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: cert-lab05-test-com
  namespace: default
spec:
  secretName: cert--secret-lab05-test-com
  renewBefore: 365h # 15d
  issuerRef:
    name: clusterissuer-test-acme
    kind: ClusterIssuer
  commonName: lab05.test.com
  dnsNames:
  - lab05.test.com

And I'm getting the following error:

I do not understand why is the challenge type dns-01 when it should be http-01 according the ClusterIssuer setup.
