windows - Unable to connect to minikube when using WSL

Question

I am testing out a kubernetes cluster on my Windows machine using minikube. I installed minikube on Windows via chocolate and I have a script to access it from wsl2. I also have installed kubectl on wsl2.

#!/bin/sh
/mnt/c/ProgramData/chocolatey/bin/minikube.exe $@

I was able to create deployments for my client and server and I can view my pods using kubectl get pods

$kubectl get pods

NAME                      READY   STATUS    RESTARTS   AGE
client-chart-deployment   1/1     Running   0          35m
server-chart-deployment   1/1     Running   0          35m

Since I am using a LoadBalancer service for my client and server I used minikube tunnel to connect to them.

$minikube tunnel

???  Starting tunnel for service server-chart-service
???  Starting tunnel for service client-chart-service

I was also able to create services for both deployments and I can view those with kubectl get serviecs

$kubectl get services

NAME                   TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
client-chart-service   LoadBalancer   10.99.57.135    127.0.0.1     3000:30741/TCP   37m
server-chart-service   LoadBalancer   10.109.66.209   127.0.0.1     4000:31539/TCP   36m
kubernetes             ClusterIP      10.96.0.1       <none>        443/TCP          4d21h

I can also view everything from minikube dashboard and minikube service list gives me the following

NAMESPACE	NAME	TARGET PORT	URL
default	server-chart-service	4000	http://192.168.49.2:30963
default	client-chart-service	3000	http://192.168.49.2:31381
default	kubernetes	No node port
kube-system	kube-dns	No node port
kubernetes-dashboard	dashboard-metrics-scraper	No node port
kubernetes-dashboard	kubernetes-dashboard	No node port

I think it's an issue in WSL2. Check these two GH Issues:
