Admin Page not accessible despite ADMIN_TOKEN

[BlackJoker90]

I am unable to access the admin page of Vaultwarden, even though I have configured the ADMIN_TOKEN in my Docker Compose file. Below is the relevant configuration for reference:

services:
  db:
    image: postgres:16
    container_name: Vaultwarden-DB
    hostname: vaultwarden-db
    mem_limit: 512m
    cpu_shares: 768
    security_opt:
      - no-new-privileges:true
    healthcheck:
      test: ["CMD", "pg_isready", "-q", "-d", "vaultwarden", "-U", "vaultwardenuser"]
      timeout: 45s
      interval: 10s
      retries: 10
    volumes:
      - /volume1/docker/vaultwarden/db:/var/lib/postgresql/data:rw
    environment:
      POSTGRES_DB: vaultwarden
      POSTGRES_USER: vaultwardenuser
      POSTGRES_PASSWORD: xxx
    restart: on-failure:5

What do you mean by "not accessible"? Is it not enabled? Or does the password you set not work? If the latter, are you using an Argon2id PHC string or a plain password?
