MQTT with HiveMQ

Agent Code
1

Hi,
I am trying to connect to via MQTT to HiveMQ cloud broker(free tier) through my agent but i constantly get:

ERROR: Failed to connect to ssl://XXXX.s1.eu.hivemq.cloud:8883 Error: Socket Error -1

Wiring it up as the docs state:

local client = mqtt.createclient();

function onConnect(resultCode) {
    // Called when the client connects (or fails to connect) to the MQTT broker
    if (resultCode == 0) {
       ..... 
    } else {
        server.error("Failed to connect to " + fullPath + " Error: " + error(resultCode) + " " + resultCode);
    }
}
.
.

client.onconnect(onConnect.bindenv(this));
local options = {};
options.username <- UN;
options.password <- PW;
        
client.connect(fullPath, cid, options);

I have used this for other apps(openhab, zigbeemqtt) without issues. Feels like i am missing something.

Any ideas?
