Error with private registry

[lepitrust]

Hi,

i use this code for build and push my dockerfile, but the push don't work...

name: ci

on:
  push:

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      - name: Set up QEMU
        uses: docker/setup-qemu-action@v3
      
      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3

      - name: Login to Private Registry
        uses: docker/login-action@v3
        with:
          registry: https://lepitrust.myqnapcloud.com:5000
          username: ${{ secrets.PRIV_REGISTRY_USER }}
          password: ${{ secrets.PRIV_REGISTRY_PASS }}
      
      - name: Build and push to local registry
        uses: docker/build-push-action@v6
        with:
          push: true
          tags: lepitrust.myqnapcloud.com:5000/pippofinance:latest 
      
      - name: Inspect
        run: |
          docker buildx imagetools inspect lepitrust.myqnapcloud.com:5000/pippofinance:latest  

At the end of build, at the moment to push the script use http instead https :( and i don't understand why...
