Certificate creation failed: 403 error for apinext.healthfirst.com

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:apinext.healthfirst.com

I applied the folloiwng code in kubect. :

apiVersion: cert-manager.io/v1
kind: Certificate
  name: mycert
  namespace: mynamespace
  secretName: mysecrete
    name: le-issuer
    kind: ClusterIssuer
  commonName: apinext.healthfirst.com
  - apinext.healthfirst.com

port 80 is working just fine.
It produced this output:

Accepting challenge authorization failed: acme: authorization error for apinext.healthfirst.com: 403 urn:ietf:params:acme:error:unauthorized: Invalid response from https://apinext.healthfirst.com/.well-known/acme-challenge/HblsIapof36toVr6lMDIEZRZ4Gp8EuXotzMAaJF39JQ:

Hi @vairakkumaar.svs, and welcome to the LE community forum :slight_smile:

Is this your first time using cert-manager?
Have you reviewed?:




Are you sure https://apinext.healthfirst.com/.well-known/acme-challenge/HblsIapof36toVr6lMDIEZRZ4Gp8EuXotzMAaJF39JQ: is offering content?

Also Certificate Transparency logs show that you have received LE Certificates in the past.


What makes you believe that, any evidence?

I see this:


The site is generating cert through cert-manager. The acme container responds for the wellknown challenge.
It looks like a config issue. Will investigate further.

I have been using cert-manager before. I am setting up a new environment and having this challenge.
