Trying to connect to Beebotte that I use as a broker, but it seems to be an issue. Has anyone else testet this broker?

This is also in the logs. "INFO: 2023-11-29 15:02:25.734287: MqttClientWrapper: mqtt-client::NoConnectionException: The maximum allowed connection attempts ({3}) were exceeded. The broker is not responding to the connection request message (Missing Connection Acknowledgement?"

I have done some testing today and it seems this is related to SSL/TLS that is not supported as far as I can see. Would it be possible to add support for SSL. Se here for an example: https://github.com/shamblett/mqtt_client/blob/master/example/mqtt_server_client_secure.dart
