MQTT 3.1.1 KeepAliveInterval different value

Hi,

I have a device that sends measurement data via MQTT 3.1.1 to AWS.
I have issues that the device connect with a different Keepaliveinterval.
It was set at 0 during initialization but had 2 in operation.

Do you know anything about this issue?
Any help would be appreciated .

Attached below is a document that summarizes the packet logs and the behavior at the time the problem occurred.

Best regards,

Ryota
