ssl error

I used hypercorn + sanic to use the http2 function, but after a while an error occurred:

	File "/usr/local/python3.12.0/lib/python3.12/site-packages/hypercorn/asyncio/run.py", line 110, in _server_callback
	await TCPServer(app, loop, config, context, lifespan_state, reader, writer)
	File "/usr/local/python3.12.0/lib/python3.12/site-packages/hypercorn/asyncio/tcp_server.py", line 76, in run
	await self._close()
	File "/usr/local/python3.12.0/lib/python3.12/site-packages/hypercorn/asyncio/tcp_server.py", line 119, in _close
