Research direction

Reproduce with Windows 11 using dotnet run --project src/AppHost after installing src/PythonInference/requirements.txt. Start by inspecting the python-inference service setup and the reported proxy bind failure on port 62394; done means the project starts successfully or the Windows/Podman limitation and workaround are documented.

Written by the indexing model from the issue text.

Description

The exception: Could not start the proxy for the service: listen tcp [::1]:62394: bind: An attempt was made to access a socket in a way forbidden by its access permissions

I could restore the Python project using pip install -r src/PythonInference/requirements.txt, but when I tried to run dotnet run --project src/AppHost, then it threw the exception like the above.

I followed the guidance at https://github.com/dotnet/eShopSupport/issues/19 for the system without GPU.
Could anyone shed light on it? Thanks very much.

My OS: Windows 11
.NET 8.0.304
Python 3.12.5
Podman
