ArgoCD with Istio returning 404

Question

Hi I am using Istio for traffic management (among other things) on AKS. Because I am terminating SSL on the gateway (no passthrough), I add the --insecure and --staticassets flags to the Deployment. I have also set the server.basehref value to /argo. Whenever I visit the /argo I see 404 responses in the Network tab on Chrome, what am i doing wrong

I am also currently using the gateway to expose Kibana, Kiali and Keycloak. I have also tried adding a DestinationRule to disable TLS on the argocd-server service. In addition to a few 404s (static assets like css)

Here is the Istio specs:

apiVersion: networking.istio.io/v1beta1
kind: Gateway
metadata:
  name: global-gateway
  namespace: istio-system
spec:
  selector:
    app: istio-ingressgateway
  servers:
  - hosts:
    - <FQDN>
    port:
      name: http
      number: 80
      protocol: HTTP
    tls:
      httpsRedirect: true
  - hosts:
    - <FQDN>
    port:
      name: https-443
      number: 443
      protocol: HTTPS
    tls:
      credentialName: wildcard-tls
      mode: SIMPLE

    route:
    - destination:
        host: argocd-server.argocd.svc.cluster.local
        port:
          number: 80

Answer 1

I forgot to set the --basehref and --rootpath flags on argocd-server. I also removed the rewrite rule.
