Simple Traefik reverse proxy configuration - traefik

Question

I'm starting up Traefik version 2.1.4 with the following configuration:
defaultEntryPoints:
- http
entryPoints:
hole-1:
address: ':663'
frontends:
hole-frontend-1:
backend: hole-backend-1
entrypoints:
- hole-1
backends:
hole-backend-1:
servers:
hole-server-1:
url: 'http://11.23.24.1:3000'
weight: 10
When I hit the http://11.23.24.1:663 I'm hit with the Traefik page 404 pages not found. When I go to http://11.23.24.1:3000 in the browser, it works, it displays the page.
I can't seem to figure out how to set up a reverse proxy in Traefik to point http://11.23.24.1:663 to http://11.23.24.1:3000.
I tried this, but I get the error
2020/02/18 11:39:43 command traefik.exe error: no valid configuration found in file: C:\config\traefik.yaml
http:
routers:

C:\config\traefik\traefik.yaml:
entryPoints:
hole-1:
address: ":661"
providers:
file:
filename: C:\config\traefik\dynamic.yaml
C:\config\traefik\dynamic.yaml:
http:
routers:
hole-router-1:
rule: "Path(`/`)"
entryPoints:
- hole-1
service: hole-service
services:
hole-service:
loadBalancer:
servers:

I started Traefik with: traefik.exe --configFile=C:/config/traefik/traefik.yaml
