But when I check the Json file on the server data folder outside assets,which I upload later into github webpage I can see the bundle there.I don't know why the error showing - HTTP/1.1 404 Not Found. as the data is still there in the Json file(Parts of the json file given beow).

From one scene I login and reach another scene. So in that scene there is an empty GameObject where I attach the below script.At start I am trying to do the AsyncOperation.
I believe in the Start method itself the exception is encountered.

Code (CSharp):

1.  
2. void Start()
3.     {
4.        // 'Label name given------ 'Models'
5.         Addressables.LoadAssetsAsync<GameObject>("Models", OnLoadDone);
6.  
7.     }
8.  
9. //Initially just trying to print names of the GameObjects
10.     private void OnLoadDone(GameObject obj)
11.     {
12.         LoadedAssets.Add(obj);
13.  
14.         Debug.Log("Count  " + loadedAssets.Count);
15.         for (int i = 0; i < loadedAssets.Count; i++)
16.         {    
17.             Debug.Log("Load Assets name " + loadedAssets[i].name);
18.             //Instantiate(loadedAssets[i]);
19.         }
20.     }
