OK, this is a different story: you want to access Web-Admin on port 4444. This one does not use the proxy at all.

You have to get the "WebAdmin certificate CA" and import it to your browser.

I don't want to offend you, but are you sure, you did it the right way?

You tell us "I did it", but we do not know where you have a problem following the guides or docs.

Otherwise, if you strictly followed the docs or KB articles, this would work.
