restore subscriptions after connection lost about gmqtt HOT 4 CLOSED

The exception is also due to this 90766b0#r36865808 in v0.5.5.

from gmqtt.

Turns out that the subscriptions it not established in the first place. I'm using an asyncio routine for that which is waiting for the connection to be established inside of a MQTTClient subclass:

await self._connected.wait()
self.subscribe(topic, qos=qos)

The subscription happens right before the connection crashes (see above). But after the connection is lost, no message go through to the subscription.

@HerrMuellerluedenscheid WARNING:gmqtt.mqtt.handler:[EXC OCCURED] in reconnect future None is buggy logging 😞 as @miili mentioned. Today new version0.6.0 is released, it's fixed there.
Wether subscriptions are alive or not depends on the session life time. You can manipulate session with parameters clean_session parameter and sssion_expiry_interval connect property.

@HerrMuellerluedenscheid I will close the issue. If you have further questions, please reopen.
