Addressables WebGL & loading Remote Scenes

Hi all,
I'm trying to work with addressables specifically, w WebGL builds & loading remote scenes from a server

Works in Unity addressable play modes
But Not in Browser
I just get the first empty scene the next never loads


I have read that you need to Download first and then LoadScenes
something like (Pseudo code)

Code (CSharp):

1.     [SerializeField] AssetReference assetReferenceScene;
2.  
3.  
4.     void OnSomething()
5.     {
6.         //initialize:
7.         Addressables.LoadAssetAsync<Scene>(assetReferenceScene);
8.         // Intantiate:      assetReferenceScene.LoadSceneAsync(UnityEngine.SceneManagement.LoadSceneMode.Additive);
9.  
10.     }

I believe my Workflow is solid :
Loading Scenes Additively may be the best option for me to assemble a variety of assets & dependencies...

a) import addressables package and make new group (I call 'scenes') and drag the scenes I want to load inside- Note that alone makes them addressable
- and because it's a scene I don't know if I also need to include the prefabs/ models / materials & textures... but I do and also give them labels

b) I set up another profile I point to a server I control the permissions on and right click to set as the active profile
- & I make sure all my groups point to using the remotes Load and Build
- & check the √ build remote catalog button in the Addressableasset settings also

c) in my Starting (almost blank) scene, I have a (working) script to load a remote addressable scene (below)

Code (CSharp):

1.     [SerializeField] AssetReference assetReferenceScene;
2.  
3.  
4.     void OnSomething()
5.     {         assetReferenceScene.LoadSceneAsync(UnityEngine.SceneManagement.LoadSceneMode.Additive);
6.  
7.     }

- I test it in the Play mode (use asset database)
- Then I use the addressables build to build (new build > default) the remote assets to my "Server Data" folder created outside the Assets folder (n my case this is a webGL build, so it creates a webGL folder to hold my bundles .json and hash)
- After that builds I upload the (WebGL) folder to the remote server (the same file path as the remote setting I provided (above where WebGL is [build target])) & I change the permissions to be completely open so they can be accessed.
- I test it again in addressable Play mode (with use existing build) selected as this will pull the assets remotely

Thanks in advance!

All my hosting permissions of the file have been set to open,
So I even tried in a new open Bucket on Google Cloud and I am still unable to load remote content

Here is the console error:

Exception encountered in operation Resource<IAssetBundleResource>(remote_scenes_all_7daf21d27e3977a8c1cafcb8f0fd12e4.bundle), status=Failed, result= : RemoteAssetBundleProvider unable to load from url https://storage.googleapis.com/bent...s_all_7daf21d27e3977a8c1cafcb8f0fd12e4.bundle, result='HTTP/1.1 404 Not Found'.
