Question (Addressables) Unable to load asset bundle

Hi there..
I'm new to addressables, I followed this tutorial on youtube (

) and I made it, so I was able to make my prefab level downloaded from cloud at the beginning of the scene as a test. everything was fine, then I mad some changes and updated the addressable build. and from here it stopped working at all...
I tried everything, I also started all steps from beginning and no luck.
it says in unity console (RemoteProviderException : Unable to load asset bundle from : (Link)... ResponseCode : 404), I tried Unity dashboard and digitalocean to upload assets.
I'm using android platform

anyone know what is the problem here???

 

at last I did it, it was nightmare for days.
for those who have the same problem:
the steps have to be in exact specific order...
1- run setup guide in unity dashboard /LifeOps/Cloud Content Delivery, (upload any small file for now).
2- go to your bucket and copy the url with the latest badge (Not the release one).
3- put the url link in unity Addressables Profiles / RemoteLoadPath.
4- build the addressables group.
5- delete the small file (in number 1 of this steps), and upload the files from ServerData to your bucket.
6- create new release.
and you are done

* if you promoted the release => start from number 4 again and follow the steps
* if you made changes to groups => update the addressables group, then follow steps from number 5
