Try a pull in debug mode, such as docker -D pull mcr.microsoft.com/dotnet/aspnet:8.0 and it might give you some more details and hints at the possible problem. What does curl -v https://mcr.microsoft.com/dotnet/aspnet:8.0 on that same host give you? Are you using some kind of proxy? This is the most likely cause, something interfering with the connection. Check your docker info but also if your host some some global proxy or similar things enabled.

r/docker on Reddit: Cannot Pull Images from mcr.microsoft.com – EOF Error
June 8, 2025 -
[v4.42.0]
[Docker Desktop – Windows]
As the title suggests, I cannot pull any images from the mcr.microsoft.com registry.
Every time I try to pull an image (e.g., docker pull mcr.microsoft.com/dotnet/aspnet:8.0), I receive an EOF error:
Error response from daemon: failed to resolve reference "mcr.microsoft.com/dotnet/aspnet:8.0": failed to do request: Head "https://mcr.microsoft.com/v2/dotnet/aspnet/manifests/8.0": EOF
Any advice would be appreciated, as I’ve been trying to fix this issue for hours. I even reinstalled Docker Desktop. Both ping and curl to the MCR registry work without issues.
[Solved]
It seems that the main issue was in ipv6 communication. For some reason Mcafee antivirus was blocking it for the MCR.

January 14, 2021 - The Docker image names are shortened in that graphic, they’re all hosted on MCR so they all need to be prefixed with mcr.microsoft.com/. The tag for each is the latest release, so that’s a moving target - the :ltsc2019 Windows image is updated every month with new OS patches, so if you use that in your FROM instruction you’ll always get the current release.
