MQTT reconnection when not disconnected. ESP8266 about arduino-mqtt HOT 6 OPEN

I think the reconnection occurs after a message is sent.
(I send the uptime every 10 seconds on mqtt)
Could it have anything to do with the message being sent to QoS1?

I continue to monitor the disconnect.

I have the same problem.
!client.connect is false but my mosquitto logs says there is no disconnect of that client.
So the ESP reconnect a lot without any reason.

1706501287: New connection from 192.168.1.192:50896 on port 1883. 1706501287: Client Piridach already connected, closing old connection.

I also tried the set keepalive up and also moved my mosquitto server from my pi to my nas, but it does not change anything.
I have other clients like tasmota connected to the mosquitto server without any problems.
Also my network is stable without any drops.
It has nothing to do with publish things. It just happens in standby while looping over client.loop();
So i´m out of ideas...........

Make sure the client IDs are not the same, please.

When using "Arduino," it's better to use a client ID that no one else is likely to use.

If there is a duplicate client ID, it will immediately disconnect from the broker, and because it disconnects, the ESP32 will attempt to reconnect.

This will continue endlessly. Additionally, if it is used for subscribing, just subscribe to one topic using a wildcard, for example, ex/#. This way, all topics starting with ex will automatically be subscribed.

In my case the problem was caused by QOS1.
Currently, the library cannot handle QOS1, and this is what caused me to lose the connection.
Since I set it to QOS0 the problem has disappeared.
