Docker Desktop ignores manual proxies #12714

• I have tried with the latest version of Docker Desktop
• I have tried disabling enabled experimental features
• I have uploaded Diagnostics
• Diagnostics ID:

Actual behavior

Docker Desktop ignores manual proxy settings set through the UI.

Expected behavior

Docker Desktop should honor manual proxy settings set through the UI.

Information

• Windows Version: 11, 21H2
• Docker Desktop Version: 4.8.1
• WSL2 or Hyper-V backend? WSL2
• Are you running inside a virtualized Windows e.g. on a cloud server or a VM: No

This is reproducible for me every time. The problem has happened for me in every version after 4.6.0.

Steps to reproduce the behavior

1. Configure http and https proxies in Docker Desktop
2. Try to pull an image
3. Note that it fails.

This issue occurs for me in 4.8.1 and I had to roll all the way back to 4.6.0 to make this work.
