Connection error: Unable to connect to echo.websocket.org on port 443, error: no error

Trying the example code on macOS and it throws the above error.
Version 11.4.5
Apple M3 Pro
Sonoma 14.6 (23G80)

Seems this does the trick:
def config_options(self):
self.options["ixwebsocket"].tls = "applessl"

But the default:
default_options = {
"shared": False,
"fPIC": True,
"tls": "mbedtls",
"with_zlib": True,
}
