Rasa : Aws bucket model server bad zip file error

I am using Rasa Nlu server and aws bucket to host the trained models. I am trying to access the models from another rasa server. Basically I have 2 servers. one for training and another for parsing.

What is the best way to load the models to parse from another server? I am not able to figure this out :frowning:

I setup an endpoint config and mentioned in doc and when i run this command

python -m rasa_nlu.server --config config.yml --path https://s3.region.amazonaws.com/bucket-name/my-models --endpoints /path_to_file/model-config.yml

It throws an error

    File "/anaconda3/lib/python3.6/zipfile.py", line 1175, in 
    raise BadZipFile("File is not a zip file")
    zipfile.BadZipFile: File is not a zip file

My model server config file has model: url: “https://s3.region.amazonaws.com/buket-name/models-folder/”
