Hello @Desmond Sindatry , Welcome to the Microsoft Q&A forum.
Azure Load balancer does not support WebSockets. You can consider using Application Gateway as it natively supports WebSockets. You can explore Application Gateway Ingress Controller (AGIC) which is a Kubernetes application, which makes it possible for Azure Kubernetes Service (AKS) customers to leverage Azure's native Application Gateway L7 load-balancer to expose cloud software to the Internet.
If it helps you can go through this documentation to help decide on a load balancing solution for your scenario.
Please let me know if you have any additional questions. Thank you!
