After following all the steps to install rancher and rke, using either rancher generated certificates or let’s encrypt, getting kubernetes ingress controller fake certificate.

Rancher is up and running

Hi @ntomas, I am having the same issue. Did you find any solution for this?

It looks like cert-manager hasn’t created the certificate.
Please review the troubleshooting guide https://cert-manager.io/docs/faq/acme/
