I have a strange situation where sometimes a request hits an ingress and sometimes hit another ingress. I know because it comes with a different SSL certificate, and when it happens, there is no log on the ingress.

Is there some way to debug this? Get the logs from the load balancer and see what happens, and which route it takes?
