Question Website recieving no data as response

I'm trying to get started with networking and so I have hosted a website that just echos a basic hello world and I have copy and pasted the unitywebrequest.get() example but for some reason it's always returning "Received no data in response". Here's the link for my website, http://caldyonstudio-lifesim.epizy.com/WhatsUp.php

The code for the php is,

<?php

echo "What up dawg?";

?>

And the script I'm using in unity is...




using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;

public class network_getMessage : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
StartCoroutine(GetMessage());
}

IEnumerator GetMessage()
{
UnityWebRequest www = UnityWebRequest.Get("http://caldyonstudio-lifesim.epizy.com/WhatsUp.php");
yield return www.SendWebRequest();

if (www.result != UnityWebRequest.Result.Success)
{
Debug.Log("Error: " + www.error);
}
else
{
// Show results as text
Debug.Log(www.downloadHandler.text);
}
}
}
