I have tested the latest-qe images on OCP4 AWS cluster.
All installation steps completed successfully. I see the following gateway issues:

• bookinfo product page cannot be accessed from istio-ingressgateway route + /productpage endpoint

How to produce this issue:

• Set up OCP4 AWS cluster
• Deploy operators and istio contorlplane
• Deploy bookinfo and try to access the product page from istio-ingressgateway route + /productpage endpoint

RCA:

This issue is related the restrict ports in a CR.
We cannot use the following lines in a CR now.
port: 80
targetPort: 80
name: http2
port: 443
name: https

The port 80 should be configured as targetPort: 8080 and port 443 should be configured as targetPort: 8443.
