i'm trying to setup a docker registry + ui. the problem is i'm running in some troubles using authentication and i don't know where to look for anymore or why it's failing in the first place.

this is my compose file:

version: "3"
services:
  registry:
      image: registry:3
      container_name: registry
      ports:
        - 5000:5000
      environment:
        REGISTRY_AUTH: htpasswd
        REGISTRY_AUTH_HTPASSWD_REALM: Registry Realm
        REGISTRY_AUTH_HTPASSWD_PATH: /auth/.htpasswd
        REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY: /data
        REGISTRY_HTTP_HEADERS_Access-Control-Allow-Origin: '[http://registry:5000]'
        REGISTRY_HTTP_HEADERS_Access-Control-Allow-Methods: '[HEAD,GET,OPTIONS,DELETE]'
        REGISTRY_HTTP_HEADERS_Access-Control-Allow-Credentials: '[true]'
        REGISTRY_HTTP_HEADERS_Access-Control-Allow-Headers: '[Authorization,Accept,Cache-Control]'
        REGISTRY_HTTP_HEADERS_Access-Control-Expose-Headers: '[Docker-Content-Digest]'
        REGISTRY_STORAGE_DELETE_ENABLED: 'true'
      restart: unless-stopped
      volumes:
        - registry-data:/var/lib/registry
        - auth_data:/auth

  registry-ui:
    image: joxit/docker-registry-ui:latest
    container_name: docker_registry_ui
    ports:
      - "8080:80"
    environment:
      REGISTRY_TITLE: "My private Docker Registry"
      SINGLE_REGISTRY: 'true'
      DELETE_IMAGES: 'true'
      SHOW_CONTENT_DIGEST: 'true'
      NGINX_PROXY_PASS_URL: http://registry:5000
      SHOW_CATALOG_NB_TAGS: 'true'
      CATALOG_MIN_BRANCHES: '1'
      CATALOG_MAX_BRANCHES: '1'
      TAGLIST_PAGE_SIZE: '100'
      REGISTRY_SECURED: 'false'
      CATALOG_ELEMENTS_LIMIT: '1000'
    restart: unless-stopped

volumes:
  registry-data:
  auth_data:
 

I check for the volume if it is mounted and if it is correct

so locally I have /var/lib/docker/volumes/auth-data/_data/htpasswd

inside my container using docker exec -it I also have an htpasswd file in /auth/htpasswd

(htpasswd refers to the file not a folder)

i check both files the content and it is correct. then i check my password using htpasswd also correct.

when trying docker login http://localhost:5000 i get unauthorized as response no matter what i tried I always have that response.since the password is correct and seems to be mapped i'm out of ideas where to look for. Any help is welcome.
