Remove Image Tag from Self-managed External Registry in Self-managed Gitlab

Hello, i have problem with deleting image tag from gitlab that use external registry (installed on different server).

Here’s my docker-compose.yml for gitlab

services:
  app:
    image: gitlab/gitlab-ee:${VERSION}-ee.0
    container_name: ${CONTAINER_NAME}
    restart: always

*EXTERNAL_REGISTRY=http://192.168.0.2:5000 (it on different server with gitlab)

and my config.yml for registry is

version: 0.1
log:

    service: registry
storage:

    enabled: true
  cache:
    blobdescriptor: inmemory

i can remove image tag using postman with DELETE method
http://192.168.0.2:5000/v2/<my-project>/manifests/<digest>

i can remove it too using registry-ui that i installed on same server with registry (192.168.0.2:5001)

but when i try to remove it with gitlab, i got this error

i don’t know what exactly the error is, or maybe just misconfigured on config.yml for registry / compose config for gitlab?
