Troubleshooting Jitsi Disconnection Issues when Multiple Participants Join

Question

I am currently working on a personal project to better understand Kubernetes and Jitsi, and I could use some help with my setup. I am not a member of any organization, so I am turning to the Jitsi community for assistance.

I have attached my YAML files and would appreciate it if someone could review them and let me know if there are any configuration elements that may be missing. I am running this setup on my local machine, using minikube on Ubuntu, which is deployed on a VMware workstation. I have noticed that multiple participants can join and engage in chat via Firefox and Chrome, but they are unable to see or hear each other.

I am new to both Jitsi and Kubernetes, so please excuse any perceived lack of expertise. Any advice or suggestions would be greatly appreciated. Thank you in advance for your help.

I attempted to configure jvb, prosody, and jicofo, but none of these configurations have been successful. Despite trying with just one jvb, the system is still failing. I suspect that this may be an issue with the version, and therefore attempted to use the latest Jitsi images. However, I encountered a WebSocket error, which appears to be resolved through the use of a public URL. Unfortunately, I do not have ownership of a domain and am thus unable to test this solution. I kindly request any assistance that may be available.
