AIOHTTP Errors with SSL

Question

I am testing a simple AIOHTTP server inspired by this documentation and this answer:

async def handle(request):
    name = request.match_info.get('name', "Anonymous")
    text = "Hello, " + name
    print(text)
    return web.Response(text=text)


app = web.Application()
app.add_routes([web.get('/', handle),
                web.get('/{name}', handle)])
ssl_context: SSLContext = create_default_context(purpose=Purpose.CLIENT_AUTH)
ssl_context.load_cert_chain(certfile=<my cert file>)

if __name__ == '__main__':
    web.run_app(app, ssl_context=ssl_context)

and I keep getting this error after a while:

Exception in callback _ProactorBasePipeTransport._call_connection_lost(None)
handle: <Handle _ProactorBasePipeTransport._call_connection_lost(None)>
Traceback (most recent call last):
  File "C:\Program Files\Python310\lib\asyncio\events.py", line 80, in _run
    self._context.run(self._callback, *self._args)
  File "C:\Program Files\Python310\lib\asyncio\proactor_events.py", line 162, in _call_connection_lost
    self._sock.shutdown(socket.SHUT_RDWR)
ConnectionResetError: [WinError 10054] Une connexion existante a dû être fermée par l’hôte distant

The error doesn't appear when I do not use SSL.

Note that everything else seems to work fine:

Any insight would be much appreciated, thanks.
