Issues with UnityWebRequest GET on Android

Hi everyone and thanks for your help!

I am trying to ask my web application if a user is ok to connect or not and I am currently struggling with webrequest on android.

First I worked with HttpWebRequest and it looks like this does not work on Android (code below) :

private bool TryConnect(string email, string password) {
        var cert = new ForceAcceptAll();

        string siteAddress = webSiteAddress + $"/Account/LoginSmartphone?email={email}&password={password}";

        HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(siteAddress );
        webRequest.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
        webRequest.Method = "GET";
        using (HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse()) {
            var html = new StreamReader(response.GetResponseStream()).ReadToEnd();
            bool.TryParse(html, out bool connectionOk);
            return connectionOk;

It worked perfectly on computer but I had no response on Android. So after searching on Google I found this solution instead :

    IEnumerator GetRequest(string uri) {       
        using (UnityWebRequest webRequest = UnityWebRequest.Get(uri)) {
            Debug.Log("Before send request");
            //webRequest.certificateHandler = new ForceAcceptAll();
            // Request and wait for the desired page.
            yield return webRequest.SendWebRequest();

            Debug.Log("Send request done");

            switch (webRequest.result) {
                case UnityWebRequest.Result.ConnectionError:
                case UnityWebRequest.Result.DataProcessingError:
                case UnityWebRequest.Result.ProtocolError:
                    //Error in login
                    Debug.LogError("Error: " + webRequest.error);
                case UnityWebRequest.Result.Success:
                    Debug.Log("Received: " + webRequest.downloadHandler.text);
                    if (ConnectionResponse(webRequest.downloadHandler.text)) {
                    } else {

On computer it works perfectly but when running on Android Emulator I have a timeout everytime. I hit the Debug.Log(“Before send”) but never the Debug.Log(“Send Request done”).

Does anyone know why is that and how to manage it properly?

Thanks and have a nice day!
