Issue with HTTP about ring-hassio HOT 1 OPEN

update on what i have tried, moved this to Nginx , so that in the lan, now i am able to access the HTTP page of HA.
from outside home, i can reach via HTTPS.
that said browsing to port 3000 still doesnt work

Logs:

Error getting new camera image from Front Door: Cannot connect to host :3000 ssl:default [Connect call failed ('', 3000)]

the name of camera matches what is in Ring app
Error opening stream http://:3000/public/stream.m3u8

Connection to tcp://:3000 failed: Connection refused

Any further thoughts on why this isnt working?

Config file:

ring:
username: !secret ring_username
password: !secret ring_password

camera:

• platform: generic
  name: Front Door
  stream_source: http://:3000/public/stream.m3u8
  still_image_url: http://:3000/public/stream.m3u8
