The external IP of istio ingress gateway stay pending
I deployed a istio to k8s and it works well at first, but after one day, I can't access the app via ingress gateway. Then checked the istio svc status. It shows the external ip of the istio ingress gateway is pending.
I checked logs and events of the service, but there is nothing. What's the most possibility cause of the issue?

This is most likely caused by using platform that does not provide an external loadbalancer to istio ingress gateway.
According to istio documentation:
If the
EXTERNAL-IPvalue is set, your environment has an external load balancer that you can use for the ingress gateway. If theEXTERNAL-IPvalue is<none>(or perpetually<pending>), your environment does not provide an external load balancer for the ingress gateway. In this case, you can access the gateway using the service’s node port.
You can follow the linked documentation guide where it is explained how You can connect to Istio ingress using nodeport instead.
