An error is reported by the python connection interface
as follows:

aiohttp.client_exceptions.ClientConnectorCertificateError: Cannot connect to  host:443 ssl:True [SSLCertVerificationError: (1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1056)')]

SSL handshake failed on verifying the certificate
protocol: <asyncio.sslproto.SSLProtocol object at 0x000000B1D4E2A7F0>
transport: <_SelectorSocketTransport fd=708 read=polling write=<idle, bufsize=0>>

Solution:

# conn = aiohttp.TCPConnector(verify_ssl=False)  # Prevent ssl from reporting errors
async with aiohttp.ClientSession(connector=aiohttp.TCPConnector(limit=64,verify_ssl=False)) as session:

Add verify_ SSL = false.
