I’m developing Remote TV Control app for iOS with Swift, now I’m trying to add support for Hisense TVs working on VIDAA OS, I researched and understood that it is working with MQTT broker, I tried different packages to setup connection with TV, mainly CocoaMQTT package, but something went wrong, I used 36669 port to connect.

Would like to listen any best practices regarding that.

let clientID = "CocoaMQTT-" + String(ProcessInfo().processIdentifier)
let mqtt5 = CocoaMQTT5(clientID: clientID, host: "broker.emqx.io", port: 1883)

let connectProperties = MqttConnectProperties()
connectProperties.topicAliasMaximum = 0
connectProperties.sessionExpiryInterval = 0
connectProperties.receiveMaximum = 100
connectProperties.maximumPacketSize = 500
mqtt5.connectProperties = connectProperties
mqtt5.enableSSL = true    
mqtt5.allowUntrustCACertificate = true
mqtt5.username = "hisenseservice"
mqtt5.password = "multimqttservice"
mqtt5.keepAlive = 60
mqtt5.delegate = self
mqtt5.connect()

I recieve this error:

The operation couldn’t be completed. (kCFStreamErrorDomainSSL error -9824.)

Maybe this approach is not correct to connect with Hisense TVs in Local Network. For example: For Samsung TVs I connected, with wss://<ip_address>:8002/ms.remote.control…
for LG TVs: wss://<ip_address>:3001/…
Now want to know the correct approach for Hisense TVs with VIDAA OS

UPDATE:
This is what CocoaMQTT logs in debug mode:
