Istio Ingress Gateway issue

– This is deployed in Rancher.

The ingress is done using istio. Yesterday Istio was updated to latest version, 1.4.4.

Istio ingress is installed as NodePort (31380 port for http); at this moment all requests to the ingress are returning connection refused.

We have noticed that there is no listener on IPV4 only on IPV6 for port 31380; this is why all requests are returning connection refused.

Since the only relevant change was the update from 1.4.3 to 1.4.4, we suspect that this is the cause.

There is never a listener for port 31380, if your configs work well there is a listener for the port defined in the gateway server
