I'm trying to get letsencrypt/cert-manager running via this Helm chart. The K8s cluster is on Digital Ocean.
I successfully verified the installation as recommended and have created a ClusterIssuer for staging, and 1 for production. (letsencrypt-staging, letsencrypt-prod)
Problem: The acme challenge returns a 404 error.
$ k get challenge -o wide
NAME STATE DOMAIN REASON AGE
myapp-cert-2315925673-2905389610-1118496475 pending myapp.example.com Waiting for http-01 challenge propagation: wrong status code '404', expected '200' 7m55s
The Ingress works fine with port 80 when the tls block commented out. When I define tls however, requests on port 80 return a 404, which is probably why the challenge is failing.
Note: I get the same response when using my production ClusterIssuer.

:: edited to add more configs ::
After adding more configs and logs as requested by @Tubc, it appears that Nginx is throwing an error when I update the ingress because the cert doesn't exist.
