TLS to protect Docker Daemon not working on Win - where to look in diagnostics files?

Question

Anyone know where to look within the various Docker diagnostics files to diagnose why TLS is not working to protect the Docker Daemon on Docker Desktop for Windows?

Tried the following article from Docker and countless other articles to try to protect the Docker Engine using a self-signed TLS cert on Windows, but none have worked.

Use TLS HTTPS to Protect the Docker Daemon Socket

https://docs.docker.com/engine/security/protect-access/#use-tls-https-to-protect-the-docker-daemon-socket

Docker Desktop for Windows versions tried: 2.3.0.4, 3.2.0

OS: Windows 10

The general log file that is produced doesn’t provide a clear answer to the root cause of the issue. Are there certain files within the diagnostic files, which are generated, that might provide better insight as to why TLS is not working?

Thanks!

You can enable debug messages on either the command line or add them to daemon.json

command line

dockerd --debug

daemon.json

{
    "debug": true
}

On windows the output will go to the Event Viewer.
