<p>I'm getting lots of errors on one of my K8s worker nodes saying &quot;http: TLS handshake error from some_ip:port: remote error: tls: bad certificate&quot;, but I'm not having any problems using any of my K8s containers.  The problem is being logged in /var/log/syslog seems to be specific to one particular K8s node.</p>
<p>I assume I need to update a certificate, but I'm not sure if it's something in /etc/kubernetes/pki or /var/lib/kubelet/pki.</p>
<p>I assume it's related to the cni0 interface, since that's the subnet that matches the .</p>
<p>Does anybody know what it means, or better yet, how to fix it?</p>
<p>Thanks in advance!</p>

<p>This is more likely coming from the cert-manager.
You can find this from cert-manager-webhook- pod, usually in cert-manager namespace.</p>
