kCFStreamErrorDomainSSL Code=-9806 "(null)"... When trying to connect via one way SSL.

[raghavgautam123]

I'm not able to connect to my server using one way TLS.

The code I use to connect is : self.mqttClient = CocoaMQTT(clientID: clientId, host: host, port: UInt16(port)) self.mqttClient.keepAlive = 15 self.mqttClient.autoReconnect = setAutomaticReconnect self.mqttClient.delegate = self self.mqttClient.enableSSL = true self.mqttClient.allowUntrustCACertificate = true self.mqttClient.connect()

This returns error: Optional(Error Domain=kCFStreamErrorDomainSSL Code=-9806 "(null)" UserInfo={NSLocalizedRecoverySuggestion=Error code definition can be found in Apple's SecureTransport.h})

If I comment out enableSSL and allowUntrustCACertificate, it works perfectly. Server is EMQX based and works fine with all the other libraries for TLS operations except this one.

Any help by the maintainers would be appreciated. I'm kinda stuck.

I tried commenting as well as setting enable SSL to false and allowUntrustCACertificate to true. Still the same.

Add this in your CocoaMQTTDelegate

    func mqtt(_ mqtt: CocoaMQTT, didReceive trust: SecTrust, completionHandler: @escaping (Bool) -> Void) {
        completionHandler(true)
    }

[harshsurati]

This delegate is already there and has completion true also.

What is happening now is.

[TRACE] [didDisconect]: Error Domain=GCDAsyncSocketErrorDomain Code=7 "Socket closed by remote peer" UserInfo={NSLocalizedDescription=Socket closed by remote peer}
[TRACE] [didStateChangeTo]: new state: connecting
[TRACE] [didDisconect]: Error Domain=kCFStreamErrorDomainSSL Code=-9806 "(null)" UserInfo={NSLocalizedRecoverySuggestion=Error code definition can be found in Apple's SecureTransport.h}

This happen 1 in 20 times. Rest is working fine.

Did you find a solution to this problem ?
