Failed to connect to 8883

[SkyOfFeather]

When I connected to 1883, the connection was successful, but when I connected to 8883(enableSSL=false), the connection failed with the error 'Socket closed by remote peer'. When I set enableSSL to true, there will also be an error: "Error Domain=kCFStreamErrorDomainSSL Code=-9806" (null) "UserInfo={NSLocalizedRecoverySuggestion=Error code definition can be found in Apple's SecureTransport. h}".

I am testing the iOS 15.1 system. Here is my code:

        let mqtt5 = CocoaMQTT5(clientID: clientId, host: brokerHost, port: 8883)

        let connectProperties = MqttConnectProperties()
        connectProperties.topicAliasMaximum = 0
        connectProperties.sessionExpiryInterval = 0
        connectProperties.receiveMaximum = 100
        connectProperties.maximumPacketSize = 500
        mqtt5.connectProperties = connectProperties

        mqtt5.username = username
        mqtt5.password = password
        mqtt5.willMessage = CocoaMQTT5Message(topic: "/will", string: "dieout")
        mqtt5.keepAlive = 60
        mqtt5.autoReconnect = true
        mqtt5.allowUntrustCACertificate = true
        mqtt5.cleanSession = true
        mqtt5.enableSSL = false
        mqtt5.delegate = self
        let result = mqtt5.connect(timeout: 10)
        print("调用结果: \(result)") 

With the same parameters, I can successfully connect on the mqttx tool. Here is a screenshot of mqttx：

There is a place to set mqtts://on mqttx. How can I modify the code to achieve the same effect?

Sorry. There is no useful information, Maybe you can find some information from CocoaMQTTCONNACKReasonCode in MqttDecodeConnAck callback. Thanks.

Please refer to this demo CocoaMQTT_reply.zip

I have the exact same issue if anyone has any suggestions. That Zip just seems like the repo?
