Pulling image from Dependency proxy returns 503

GitLab CI/CD
1

We are implementing usage of dependency proxy in our pipeline but we receive the following error for some images.

If we attempt to pull the image alpine:latest Then it works without any issues.

If we attempt to pull the image mcr.microsoft.com/dotnet/sdk:latest Then we receive the following error:

ERROR: Job failed: failed to pull image “gitlab.com:443/company/dependency_proxy/containers/mcr.microsoft.com/dotnet/sdk:latest” with specified policies [always]: Error response from daemon: received unexpected HTTP status: 503 Service Temporarily Unavailable (manager.go:203:0s)

The step is as simple as:

**Working example**
Dependency Proxy Test:
  stage: .pre
  image: ${CI_DEPENDENCY_PROXY_GROUP_IMAGE_PREFIX}/alpine:latestt
  script:
    - echo "Test"

**This yields an error**
Dependency Proxy Test:
  stage: .pre
  image: ${CI_DEPENDENCY_PROXY_GROUP_IMAGE_PREFIX}/mcr.microsoft.com/dotnet/sdk:latest
  script:
    - echo "Test"
