@prehistoric-whale-94119 Hello anelezni, Sorry you are running into this. • Use a simple setup: EC2 (open 80/443), install K3s → install Helm → install cert-manager → install Rancher via Helm with your EC2 DNS as hostname. • Most issues come from DNS not set, port 443 blocked, or cert-manager not ready. Rancher requires HTTPS by design because it handles sensitive cluster data. You can choose your certificates (self-signed or your own), but you can’t disable TLS completely. If you share your error or setup, I can help you debug quickly.
