Kubernetes lets-encrypt Cluster Issuer

I need help fixing my SSL cert issuer as it's not properly set up. I need someone to debug & help me fix it. Current issue i'm having is: solver configuration for domain "[login to view URL]" not found. Ensure you have configured a challenge mechanism using the [login to view URL] field. I have setup my ingress & I have some domains that work already, I just need a way to make it automatic in future releases. Please make sure you have experience with kubernetes / rancher / letsencrypt before contacting me.
