Nested WebDriver Causing Connection to Abort (WinError 10053: An established connection was aborted by the software in your host machine)

For some reason I get the following error only when I open up a nested webdriver instance. No idea what is happening here.
I am using Windows 10, and geckodriver 0.21.0.
ConnectionAbortedError: [WinError 10053]

An established connection was aborted by the software in your host machine

Does anybody have any idea whatsoever what might be causing the connection to abort?
