Unable to Connect to Web Interface via nonstandard port

[SxthGear]

Docker-Compose.yaml

version: "2.1"
services:
  kasm:
    image: kasmweb/workspaces:1.11.0
    privileged: true
    container_name: kasm
    environment:
      - KASM_PORT=4443
    volumes:
      - /docker/containers/kasm/:/opt
    ports:
      - 4443:443
      - 3099:3000
    restart: unless-stopped

Able to log into the install interface on port 3099, however connecting to the host on https://hostname:4443 yields a connection refused from the browser. Testing with setting the KASM_PORT env variable set to both 443 or 4443 with same result. No errors noted in the log for the kasm container.

I can confirm this issue. Tried to use port 9443 but could only connect when restoring the port to 443. Additionally neither of the logins user@kasm or admin@kasm are accepted.

Edit: For any future readers who decide to skip the video like me. Usernames are in the format admin@kasm.local
user@kasm.local

However the install wizard omits the .local suffix.
