Troubleshooting Internal SSL Error and HTTP 404 on Rancher UI

Rancher 2.x
1

Hello Rancher community,

I’m encountering a couple of issues with my Rancher setup and would appreciate any insights or assistance in troubleshooting. Here’s a breakdown of the problems:

  1. Internal SSL Error:
  • After deploying Rancher on my Kubernetes cluster using Cert-Manager for SSL, I’m experiencing internal SSL errors when accessing the Rancher UI. The SSL appears to be functioning correctly for the domain, but I’m still encountering this issue.
  1. HTTP 404 Error on HTTP Access:
  • When attempting to access the Rancher UI over HTTP, I’m getting a “Error 404 Not Found” response. It seems like there might be an issue with the routing or configuration.

I followed the Rancher documentation for setting up a 3-node Rancher Kubernetes cluster using Docker, with specific attention to the High Availability (HA) section (Rancher Docs: High Availability (HA)).

Has anyone encountered similar issues, and could you provide guidance on resolving these SSL and HTTP access problems? Any advice, troubleshooting steps, or relevant experiences would be highly appreciated.
