Subscriber does not receive any new messages after reconnect.

Hi,

I have a subscriber script working fine if at all there are no disconnects from the broker, but if the Connection is lost and reconnected after few seconds, It wont receive any new updates pushed to the topics its subscribed to

here is the example is used:

import asyncio

from amqtt.client import MQTTClient, ClientException
from amqtt.mqtt.constants import QOS_1, QOS_2

logger = logging.getLogger(name)
config = {
            'keep_alive': 60,
            'ping_delay': 1,
            'auto_reconnect': True,
            'reconnect_max_interval': 10,
            'reconnect_retries': 100,
        }


async def uptime_coro():
	C = MQTTClient(config=config)
	await C.connect('mqtts://localhost:8883',cafile="cert_with_ca.pem", cleansession=True)
	await C.subscribe([(str('sa/feedback_data'), QOS_1)])
	while True:
		try:
			message = await C.deliver_message()
			packet = message.publish_packet
			print( str(packet.payload.data))
		except ClientException as ce:
			logger.error("Client exception: %s" % ce)


if name == 'main':
	formatter = "[%(asctime)s] %(name)s {%(filename)s:%(lineno)d} %(levelname)s - %(message)s"
	logging.basicConfig(level=logging.DEBUG, format=formatter)
	asyncio.get_event_loop().run_until_complete(uptime_coro())```
