error 20 at 0 depth lookup: unable to get local issuer certificate

Posted on August 1, 2024

I am using DigitalOcean’s managed K8 service. I also installed CertManager and Ingress service. I go through the process to get a certificate issued by letsencrypt. But when I try to validate the cert I get the following issue:

error 20 at 0 depth lookup: unable to get local issuer certificate

How do I troubleshoot or fix this?

Hi there,

I could suggest first checking the logs to see if you would get any more information on the error:

kubectl logs -n cert-manager -l app=cert-manager

Also, verify that the Cert-Manager Pods are up and running:

kubectl get pods -n cert-manager

Along with the output of the above commands, can you share your Issuer manifest file here?
