I'm following this guide to deploy a Knative Service and used this to install Knative Serving using YAML files.
When accessing the service using:
echo "Accessing URL $(kn service describe hello -o url)"
curl "$(kn service describe hello -o url)"
The expected output is Hello World! but I'm getting the Apache 2 Default Page HTML (same result when trying to access using browser). I've looked around and tried searching for similar issues but found nothing. I'm using minikube on WSL2 and Docker Desktop. Here's a list of resources in the default namespace:

Uninstalling Apache and nginx solved this issue for me. Followed the answers here and here to completely remove the services. Hope this helps anyone who encounter the same issue.
