Question by Fabrizio_1990 · Jun 09, 2020 at 08:15 AM · download webrequest obj

UnityWebRequest work only on odd tries

I am downloading an obj runtime, but the download call work only on odd tries. if I try to download first time it work, second time is not working (don't go after yield return uwr.SendWebRequest();) the third time is working again and so on... anyone can help me?

     IEnumerator GetObjectRoutine(Action<GameObject> callback)
     {
         GameObject loadedObj = null;
         UnityWebRequest.ClearCookieCache();
         using (UnityWebRequest uwr = new UnityWebRequest("http://127.0.0.1:8887/Models/174-l2.obj", UnityWebRequest.kHttpVerbGET))
         {
             string path = Path.Combine(Application.persistentDataPath, "model.obj");
             uwr.downloadHandler = new DownloadHandlerFile(path);
             yield return uwr.SendWebRequest();
             if (uwr.isNetworkError || uwr.isHttpError)
                 Debug.LogError(uwr.error);
             else
             {
                 Debug.Log("File successfully downloaded and saved to " + path);
 
                 objectPath = path;
                 
                 loadedObj = new OBJLoader().Load(path);
                 downloadedObj = loadedObj;
                 uwr.Dispose();
             }
         }
 
         if(loadedObj != null)
             callback?.Invoke(loadedObj);
         Debug.Log("EXIT FROM GETOBJECT");
     }
