It's more commonly referred to as left libertarian these days. However it far predates right wing libertarianism. And for myself at least. I personally feel that calling original libertarianism left libertarianism, and right wing libertarianism right wing libertarianism gives right wing libertarianism far too much legitimacy.

Libertarianism is and always has been a left-wing ideology. These so-called right wing Libertarians(neo-libertarians) have much more in common with liberalism than libertarianism. And equally ironic. Those that we call liberals{neo liberals) in the United States for instance. Often have more in common with actual Libertarians than "right-wing" Libertarians do in many instances. Though there's still a good dosage of capitalist and even fascists under the moniker of the Democrats too.

The whole situation is super complex and wildly cloudy due to bottomless pockets for propagandists unfortunately.
