Template Path not working TLJH

I’m trying to modify the look of the TLJH login page.

I have TLJH running on a google cloud VM. I have copied the templates to:
/home/astrodimitrios/templates/

and edited them. I tried setting c.JupyterHub.template_paths to this new path and this is what I now see when I type sudo tljh-config show:

c:
    JupyterHub:
        template_paths: /home/astrodimitrios/templates/

Then I reload the configuration but the custom templates aren’t being used. Any thoughts? I can’t seem to access the config.yaml file either.

Thanks,
Dimitrios
