Unable to access Rancher UI "NET::ERR_CERT_INVALID"

Dear All,
I followed this link “https://rancher.com/blog/2018/2018-05-18-how-to-run-rancher-2-0-on-your-desktop/” to install RKE on my MacBook (OS Catalina 10.15.3).
It went relatively smoothly, but got the following error:

  • Deploy Cert-Manager cert-manager-v0.6.7 failed;
  • Pod “cert-manager-webhook-6fbf788df6-4b44n” stuck at ContainerCreating forever;
  • When accessing Rancher UI on https://rancher.localhost, it was unaccessible with error “NET::ERR_CERT_INVALID”

Looking forward to hearing from you!
