MQTT does not reconnect after weird connection drop


I restarted my OpenHab instance today, and during startup I saw this in the logs:

15:01:23.183 [ERROR] [ho.client.mqttv3.internal.ClientState] - OpenHAB: Timed out as no write activity, keepAlive=60.000 lastOutboundActivity=1.517.155.300.908 lastInboundActivity=1.517.155.300.919 time=1.520.085.683.106 lastPing=0

After that the connection was dropped and not reconnect anymore. Is this wanted (or at least known)?

I have the same problem. I realized that when the connection is connected but MQTTBroker does not change the state to “Connected”
