can not connect to HiveMQ Cloud Broker, SSL, no Certificate

[joersv4]

Hello,

I have a problem with the connection to the HiveMQ Cloud Broker.

This code runs on my local mqtt broker (without SSL), but not on HiveMQ Cloud Broker (with SSL).

   var mqtt: CocoaMQTT5!

    func setUpMQTT() {
        let clientID = "CocoaMQTT-" + String(ProcessInfo().processIdentifier)
        mqtt = CocoaMQTT5(clientID: clientID, host: "xxxx.s1.eu.hivemq.cloud", port: 8883)
        mqtt.logLevel = .debug
        mqtt.username = "xxxx"
        mqtt.password = "xxxx"
        mqtt.willMessage = CocoaMQTT5Message(topic: "/will", string: "dieout")
        mqtt.keepAlive = 60
        mqtt.enableSSL = true
        mqtt.allowUntrustCACertificate = true
        mqtt.sslSettings = [kCFStreamSSLPeerName as String: "" as NSObject]

        mqtt.connect()
    }

---

I can not connect to the HiveMQ Cloud Broker. I have tried everything, but nothing changed.

Wireshark of CocoaMQTT5

Wireshark of MQTTAnalyzer APP -> successful connection

So i see my app not send the "Client Key Exchange"

How can I fix this issue??

Thanks

Hi. Trying to set mqtt5!.sslSettings = [kCFStreamSSLPeerName as String: "xxxx.s1.eu.hivemq.cloud" as NSObject].

Hi.

Thank you :)

now I have found the right parameters for connection to HiveMQ Cloud.

        mqtt.enableSSL = true
        mqtt.allowUntrustCACertificate = false
        mqtt.sslSettings = [kCFStreamSSLPeerName as String: "xxxx.s1.eu.hivemq.cloud" as NSObject]

its working well with "allowUntrustCACertificate = false"
