Using STUNner project to make WebRTC connection with mediasoup in kubernetes

Cluster information:

Cloud being used: oracle public cloud
Installation method: managed by cloud
Host OS: oracle developed os for pods

Problem:
Hi, I’m trying to implement STUNner with mediasoup demo that is described in the documentation: https://github.com/l7mp/stunner/blob/main/docs/examples/mediasoup/README.md. After all the steps regarding the certificates when I’m trying to run “kubectl apply -f docs/examples/mediasoup/mediasoup-call-stunner.yaml”, the pods are scheduled behind the scenes but are not able to initialize. This yaml just consists of info to create gateway and other components related to it. Also, the intended kubernetes loadbalancer for kubernetes is also not created. There are no other steps or cmds other than the described. I’m using oracle cloud for the setup and it has the prerequisite conditions as well as resources. What might me the problem and how should I debug it?
