Those values are only used when the "settings" dictionary has no key with the given name.
And I'm using empty strings because that's what QNetworkProxy uses if no parameter is given:

Since the current version of the tunnel is not getting the authentication, I think it's safe to use it like this. Perhaps we can add a comment or a TODO for it, and we can fix it in an upcoming branch to add authentication.

Great catch! Thanks, I'm fixing it too.
