Fresh installation of Rancher Server into RKE fails

Hello together,
I am currently trying to setup a fresh rancher server installation into a single node RKE cluster. I therefore followed the descriptions in the documentation and the rancher academy. I am unfortunately stuck after installation of letsencrypt. When trying to install rancher via helm3 I get the following error:

helm3 install rancher rancher-stable/rancher --version v2.5.3 --namespace cattle-system --set --set ingress.tls.source=letsEncrypt --set

Error: unable to build kubernetes objects from release manifest: unable to recognize “”: no matches for kind “Issuer” in version “

I have tried now with cert-manger 1.1.0 and 1.0.4. Can someone give me a hint how I can resolve the issue. I have found this topic as a bug on rancher github. Unfortunately, no description of a solution.

Has been answered here :wink: Hope that helps!
