I have a k3s setup and am trying to get my ingress configured with tls but the certificates are not getting signed by the CA. The error I am getting is given below:

Has anyone faced a similar issue or can help troubleshoot this?
Summary: Tried securing k8s ingress for grafana using cert-manager and an external ACME CA but based on the certificate logs "No Challenges found for this Certificate" and "State: errored, Reason: Failed to create Order: 400 urn:ietf:params:acme:error:rejectedIdentifier: The server will not issue certificates for the identifier". I am not sure how to troubleshoot this and need some support.
