Steps to reproduce:

1. Deploy the 2.4 SM operator with Kiali 1.65

2. Create the 2.4 SMCP

3. Deploy the httpbin and gateway deployment to the bar namespace

4. Add the bar namespace to SMMR in the istio-system namespace

5. Deploy the k8's CRDs to the OpenShift cluster

kubectl get crd gateways.gateway.networking.k8s.io &> /dev/null || { kubectl kustomize github.com/kubernetes-sigs/gateway-api/config/crd/experimental?ref=v0.5.1 | kubectl apply -f -;

6. Apply the 2.4 Gateway API settings to SMCP:

spec:   
  techPreview:
    gatewayAPI:
     enabled: true

7. 

Deploy the Gateway API configuration including a single exposed route (i.e., /get):

apiVersion: gateway.networking.k8s.io/v1beta1
kind: Gateway
metadata:
name: gateway
namespace: bar
spec:
gatewayClassName: istio
listeners:
name: default
hostname: "*.example.com"
port: 80
protocol: HTTP
allowedRoutes:
namespaces:
from: All
—
apiVersion: gateway.networking.k8s.io/v1beta1
kind: HTTPRoute
metadata:
name: http
namespace: bar
spec:
parentRefs: name: gateway
namespace: bar
hostnames: ["httpbin.example.com"]
rules: matches: path:
type: PathPrefix
value: /get
backendRefs: name: httpbin
port: 8000 

Error: failed to assign to any requested addresses: hostname "gateway.bar.svc.cluster.local" not found
 
It failed to create the gateway service automatically.

Expected:

Deploy the gateway service automatically then create the connection (Gateway valid, assigned to service(s) gateway.bar.svc.cluster.local:80)
 

I have installed the 2.3 SMCP with the 2.4 SM operator, It works perfectly.
