Unity: Post Request unable to connect to destination host

I'm familiar with Unity but new to trying to communicate with servers. I'm trying to set up a login screen but I'm having troubling Posting to the server properly. The strange part is the Get is working fine, but the Post turns up the following Error : 

Cannot connect to destination host Network
UnityEngine.Debug:Log(Object)
LoginHandler:CheckForNetworkErrors(UnityWebRequest) (at 
Assets/Scripts/LoginHandler.cs:120)
<LoginUser>c__Iterator2:MoveNext() (at Assets/Scripts/LoginHandler.cs:92)
.UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

I'm using a test URL to make sure it was't an issue with the original. Both return the same error. The following code is sent once the player hits a login button. Any ideas on what im doing wrong here?

public IEnumerator LoginUser()
{
    string testURL = "https://www.google.com/";

    using (UnityWebRequest get = UnityWebRequest.Get(testURL))
    {
        yield return get.Send();

        ParseCSRF(get.downloadHandler.text);

        CheckForNetworkErrors(get);

    }

    WWWForm form = new WWWForm();
    form.AddField("username", username.text);
    form.AddField("password", password.text);
    form.AddField("_csrf", csrf);

    using (UnityWebRequest post = UnityWebRequest.Post(WWW.EscapeURL(testURL), form))
    {
        yield return post.SendWebRequest();

        CheckForNetworkErrors(post);
    }

}

public void CheckForNetworkErrors(UnityWebRequest www)
{
    if(www.isNetworkError) 
    {
        Debug.Log(www.error + " Network");
    }
    else if (www.isHttpError)
    {
        Debug.Log(www.error + " http");

    }
    else
    {
        Debug.Log("Form upload complete!" + www.downloadHandler.text);
    }
}

I have tested with the code I wrote below:

 void Start()
{
    StartCoroutine(GetCrt());
}

IEnumerator GetCrt()
{
    string testURL = "https://www.google.com/";

    using (UnityWebRequest www = UnityWebRequest.Get(testURL))
    {
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
        {
            Debug.Log(www.error);
        }
        else
        {
            Debug.Log("Get Request Completed!");
        }
    }
}

It's working fine.

For the post request you need a real form data, you can't send a post request to google.com.

Hope this help you.

Happy Coding!
