it's been a couple of weeks now that the previously working CI job in Gitlab is not working anymore. Here's the error

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

This is my CI yaml file

api_server_build_and_deploy:
  image: $CI_REGISTRY_IMAGE/ci_deploy
  stage: build
  services:
    - docker:dind

  environment:
    name: Staging
  before_script:
    - docker login -u "$DOCKER_REGISTRY_USER" -p "$DOCKER_REGISTRY_PASSWORD" $DOCKER_REGISTRY
  script:
    # omitted for brevity

and this is the base dockerfile

FROM node:20.10.0-alpine3.19

# installing essential environment
RUN apk add zip
RUN apk add git
RUN apk add docker-cli bash

# also installing angular
RUN npm install -g @angular/[email protected] # may not be needed

# installing ssh
RUN command -v ssh-agent >/dev/null || ( apk add --no-cache openssh )

VOLUME "/var/run/docker.sock:/var/run/docker.sock"

This used to work fine, has anything changed that requires some further config changes? Thanks
