unity web request unknown error webgl

WebRequest works in editor but not working in webgl.

void Start()
{
StartCoroutine(GetRequest("https://www.example.com"));
}
IEnumerator GetRequest(string uri)
{
using (UnityWebRequest webRequest = UnityWebRequest.Get(uri))
{
// Request and wait for the desired page.
yield return webRequest.SendWebRequest();

string[] pages = uri.Split('/');
int page = pages.Length - 1;

switch (webRequest.result)
{
case UnityWebRequest.Result.ConnectionError:
case UnityWebRequest.Result.DataProcessingError:
Debug.LogError(pages[page] + ": Error: " + webRequest.error);
break;
case UnityWebRequest.Result.ProtocolError:
Debug.LogError(pages[page] + ": HTTP Error: " + webRequest.error);
break;
case UnityWebRequest.Result.Success:
Debug.Log(pages[page] + ":\nReceived: " + webRequest.downloadHandler.text);
break;
}
}
}

this is the code im using it returns www.example.com in editor console and when i host it in itch.io it returns unknown error in the console
