Disconnect: The operation couldn’t be completed. Socket is not connected

[steveSarsawa-git]

I'm facing issue, like whenever i tried to established connection through Mobile data. MQTT getting disconnected automatically, and if i tried to reconnect getting below error. In android and React native iOS App is working fine. But issue i'm facing only in Swift iOS. I've tried all the possible ways, with enable ssl, without ssl. allowUntrustedCertificates and so on. But nothing is helping here
