This is usually caused by a firewall.
If works deactivating the firewall try opening the ports as documented in https://github.com/dotnet-architecture/eShopOnContainers/wiki/03.-Setting-the-eShopOnContainers-solution-up-in-a-Windows-CLI-environment-(dotnet-CLI,-Docker-CLI-and-VS-Code)
That ports have opened. but it not works. Thanks for your support

Some options more...
Try if setting windows firewall to not protect DockerNAT works for you (use your neeeded profile - I used public in the sample pic):

Hope this helps!
Thank you @eiximenis
But my machine cannot change this config. that is stupid.

This hit me as well. Should be part of "02. Setting eShopOnContainers in a Visual Studio 2017 environment" where the filewall settings are described.
@dohuyphuong It could be due to Domain policies from your company?
Your sreeshot says “Some settings are controlled by Group Policy”.
Can you check the same config in a different machine which is not in the enterprise Windows Domain?
If so, Please, try in a machine that is not within an enterprise domain with policies restricting.
Policies can impact further issues in Docker, as well.
Closing this issue as it looks it is due to a local PC configuration not being able to open the required ports in the firewall, as specified at the Wiki post for setup:
https://github.com/dotnet-architecture/eShopOnContainers/wiki/02.-Setting-eShopOnContainers-in-a-Visual-Studio-2017-environment
Feel free to open it again if it is due to a different issue.
Thanks,

@dohuyphuong, seems to be quite late, but try to change Protected Network Connections in Public Profile, not in Domain one. It was the solution in my case.
