Error with TLS cert mounting?

2022-02-28T04:00:39.117166Z     info    ads     ADS: "@" istio-ingress-848b7bd66d-xm4g2.istio-ingress-37 terminated rpc error: code = Canceled desc = context canceled

does this mean i need to create the kubernetes secret for my tls cert in the istio-ingress namespace? this is istio v1.13.
