Custom username/password do not work

[redjax]

Describe the bug
When running this compose stack with a CUSTOM_USER and PASSWORD environment variable fails:

---
volumes:
  obsidian_vaults: {}
  obsidian_config: {}

services:
  obsidian:
    image: 'ghcr.io/sytone/obsidian-remote:latest'
    container_name: obsidian-remote
    restart: unless-stopped
    ports:
      - ${OBSIDIAN_HTTP_PORT:-8080}:8080
      - ${OBSIDIAN_HTTPS_PORT:-8443}:8443
    volumes:
      - ${OBSIDIAN_VAULTS_DIR:-obsidian_vaults}:/vaults
      - ${OBSIDIAN_CONFIG_DIR:-obsidian_config}:/config

      CUSTOM_PORT: 8080
      CUSTOM_HTTPS_PORT: 8443
      KEYBOARD: ${OBSIDIAN_KEYBOARD_LAYOUT:-en-us-qwerty}
      CUSTOM_USER: ${OBSIDIAN_HTTP_USER:-obsidian}
      PASSWORD: ${OBSIDIAN_HTTP_PASSWORD:-Obsidian!}
      TITLE: ${OBSIDIAN_HTTP_PAGE_TITLE:-Obsidian.md}
    healthcheck:
      test: curl -f http://localhost:8080/ || exit 1

Commenting/removing the CUSTOM_USER and PASSWORD values skips the VNC login screen and opens Obsidian successfully, but setting any value for the basic auth username/password causes a login window to show, and the following error message:

connecting to sesman ip 127.0.0.1 port 3350
sesman connect ok
sending login info to session manager, please wait...
login failed for display 0

To Reproduce
Add CUSTOM_USER and PASSWORD environment variables to the obsidian service.

Expected behavior
The VNC authentication window should accept the values of CUSTOM_USER and PASSWORD.
