My IP address has problem downloading docker image from Microsoft

[ghassankarwchan]

Hi
This is very wired problem.
I posted my problem before on this forum but I didn’t know the details that I know now.
I am using Docker Desktop For Windows, on Windows 11 Pro, with WSL 2 integration.

I posted before that I can download any image except images from Microsoft store.
Anything from mcr-microsoft-com

I thought first that this was caused by upgrading docker from 4.36 to 4.37 version, and this is how I described my problem here in my previous post, and I didn’t get help anough on this forum since this actually was not the real problem.
As well the same problem started to happen on my second computer in my house that I use sometimes.

I found today that it is my IP address.
For the record the issue of downloading microsoft images fixed for a while, then it happened again.
I came to realize it is my IP address, when I was visiting another house and by luck I was working on my computer and I downloaded the image and I was able to download any image.
Then from my house, I used a VPN, and voila I am able to download any image from Microsfot.

I got my current IP address when I switched my ISP few months ago.
So, I am wondering if my IP address was blocked by some service?
I am using lots of services from Microsoft: Azure, Azure DevOps, Office365, Online Outlook…etc, and never had any problem.

So where is the problem with my IP address originated? Is it from Docker Desktop hub? or I should contact Microsoft?
Thanks a lot

Docker Hub is not involved when you pull images from a different registry.

The root cause can be anything in your network. Just to name a few:

• does the name resolution work?
• does a route to resolved ip exist?
• does a firewall on your router drop the packages to that particular target?
• does your network force a http proxy which is not properly configured?

Do you really have a fixed wan ip? If it’s a static ip address, it could be a blocked ip. If it’s a dynamic ip address, it’s unlikely that the whole network range of your isp is blocked (but not impossible).
