Describe the bug

If we want to run notify behind a proxy server on a path such as /notify/ currently it doesn't work.

To Reproduce

Setup a server such as (caddy)[https://caddyserver.com/download]

Using a Caddyfile config like this...

:7007 {
        respond "This request didn't make it to notify, sorry"
        redir /notify /notify/
        handle_path /notify/* {
                reverse_proxy http://localhost:8007
        }
}

Steps to reproduce the behaviour:

1. Start Caddy and notify (on default port 8007)
2. go to http://localhost:7007/notify/
3. Notify doesn't load

Expected behaviour

Should be able to run notify on this path (perhaps with a config change?)

Additional context

This stack overflow suggests using a public path
publicPath: '/app'

Maybe we set it up to always run on /notify/?
