I have this same issue. Tried several different images :(

[AnNguyen-112]

yeah, so weird that some of the other image I pull is totally normal, problem only happens with mcr.microsoft.com image

It's the same issue for me. The problem only happens with mcr.microsoft.com.

Disabling IPv6 from the network adapter fixed the issue.

Disabling IPv6 works for me too. Thank you so much!!!

[tnttb79]

Disabling IPv6 did fix the problem for me. But can anyone explain why disabling IPv6 solved the issue? Just want to know for future references. Thank you.

This is still a problem and disabling IPv6 is still a workaround, but seriously why?

Ftr, having this with multiple MCR images (e.g., devcontainers/dotnet, dotnet/sdk) and Docker Desktop versions (latest as 4.41.0).

The issue persists. Have to disable IPv6 for being able to pull images from MCR.

For my setup (Docker Desktop on Windows) I solved the problem without disabling whole IPv6 by pinning the IPv4 addresses for MCR:

PS C:\Windows\System32> $hosts = "$env:SystemRoot\System32\drivers\etc\hosts"   # expands correctly
PS C:\Windows\System32> Add-Content -Path $hosts -Value "`n150.171.70.10  mcr.microsoft.com"
PS C:\Windows\System32> Add-Content -Path $hosts -Value "`n150.171.70.10 westeurope.data.mcr.microsoft.com"
PS C:\Windows\System32> Get-Content -Path $hosts | Select-String microsoft.com

150.171.70.10  mcr.microsoft.com
150.171.70.10 westeurope.data.mcr.microsoft.com

(and removing any custom DNS settings from Docker Desktop config)

I appear to be experiencing the same issue. All efforts to pull any docker image tag for any MCR image is currently failing. As a sanity check, I confirmed that I am still able to pull other docker images without issue. Below is the terminal history showing 2 failed attempts for the Azure Function images and a successful attempt for the Postgres MCP image:

As mentioned by others, disabling IPv6 resolved the issue for me, though not a great permanent solution.

@terencet-dev from scanning some old issues, it seems you have dealt with similar issues in the past. Any ideas?

[terencet-dev]

Hi @lambdakris, apologies for the late response. Following up with our team

[stevenhvtran]

Hi @lambdakris , I'm taking a look into this. mcr.microsoft.com has dual-stack enabled so I expect IPv6 pulls to succeed. Our team suspects there may be a mismatch between IPv6 support on user's operating systems and internet service providers where the OS appears to support it, but the connection fails at the ISP level.

To confirm whether this is the case, if you're having an issue with pulling and disabling IPv6 fixed it, could you please try temporarily re-enable IPv6 and run a test using https://test-ipv6.com/? If there are errors, go to the "Tests Run" tab and expand the "Technical Info" section.

[lambdakris]

Thanks @stevenhvtran . Ran the test as requested and got the no IPv6 address detected error message (see below).

[victorfrye]

I re-enabled my IPv6 adapter and ran the test and see 10/10 score from that site, but unable to pull images from MCR still:
