The moquette server closes the connection

[Agoni-sudo]

The paho-client library repeatedly disconnects and connects when creating a client connection to moquette. This does not happen when connecting with the mqttx test tool but drops and reconnects every 8 minutes or so

Given the line

2024-10-30 14:16:17.110 INFO 30908 --- [tLoopGroup-3-19] i.m.broker.metrics.MQTTMessageLogger : Channel Inactive

I'm guessing that your connection is timing out. Can you try turning on keep-alive messages, or increasing the keep-alive frequency?

给定线路

我猜您的连接超时了。您可以尝试打开保持活动消息或提高保持活动频率吗？

public MqttConnectOptions mqttConnectOptions() { MqttConnectOptions options = new MqttConnectOptions(); options.setServerURIs(new String[]{hostUrl}); //options.setUserName(""); // options.setPassword("".toCharArray()); options.setConnectionTimeout(20); options.setKeepAliveInterval(30); options.setWill(willTopic, willData, 2, false); // 设置遗嘱消息 return options; } Is it keeplive of mqtt? On the client side, I set the heartbeat rate to 30s, but it still disconnects after a period of time

You can view this method initializeKeepAliveTimeout

[Yunustt]

The keeplive in the broker comes from the MQTT message
