android mqtts connection failed

[KrifaYounes]

I have configure my broker with SSL like this in mosquitto.conf

listener 8883
protocol mqtt
cafile /usr/local/etc/mosquitto/certs2/ca.crt
keyfile /usr/local/etc/mosquitto/certs2/server.key
certfile /usr/local/etc/mosquitto/certs2/server.crt

listener 443
protocol websockets
cafile /usr/local/etc/mosquitto/certs/ca.crt
keyfile /usr/local/etc/mosquitto/certs/server.key
certfile /usr/local/etc/mosquitto/certs/server.crt

when I try to connect using react_native_mqtt with useSSL true and my IP host I can't

{ invocationContext: undefined,
errorCode: 7,
errorMessage: 'AMQJS0007E Socket error:undefined.' }

How to use SSL with react_native_mqtt ?
