Docker proxyconnect connection refused error

How to "fix" Docker's proxyconnect connection refused error

This worked for me on an Apple M1.

Problem

docker pull docker/getting-started
Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: dial tcp 192.168.64.1:3128: connect: connection refused

Seriously WTF Docker? 🤷‍♂️

"Solution"

None of the other "solutions" related to authentication, DNS, or proxy settings worked for me.

I doubt all of these steps are necessary, but this is what I did.

1. Reset Docker app to factory settings

• Docker App > Troubleshoot > Clean / Purge data
• Docker App > Troubleshoot > Reset to factory defaults
• Docker App > Troubleshoot > Uninstall

2. Purge all things Docker from the machine

   rm -rf /Applications/Docker.app
   rm -rf ~/Library/Containers/com.docker.docker
   rm -rf ~/Library/Caches/com.docker.docker
   rm -rf ~/Library/Group\ Containers/group.com.docker
   rm -rf ~/Library/Logs/Docker\ Desktop
   rm -rf ~/Library/Preferences/com.docker.docker.plist
   rm -rf ~/Library/Preferences/com.electron.docker-frontend.plist
   rm -rf ~/Library/Saved\ Application\ State/com.electron.docker-frontend.savedState
   rm -rf ~/.docker
   sudo rm -rf /Library/LaunchDaemons/com.docker.vmnetd.plist
   sudo rm -rf /Library/PrivilegedHelperTools/com.docker.vmnetd

3. Reinstall Docker Desktop
