Routing not working as expected

I have a similar issue that I reported on this thread

Istio destination rule not working

After pulling my hairs for days, playing with all permuation and combinations. Found my mistake at: https://github.com/istio/istio/issues/9696. It was related to service named port. I had named it just “web”, updating it to “http-web”, worked for me, and everything else worked fine. Stackoverflow answer link : https://stackoverflow.com/questions/54197734/istio-destination-rule-subsets-not-working/54209833#54209833.

My port name is correct but the traffic split does not work. It works if I change the service port from 80 or 443 to some non standard port like 8181

Here is a the bug I opened Port 80/443 not working with virtual service · Issue #19835 · istio/istio · GitHub

This complete yaml file will reproduce the issue hello-both-http-port.yaml
