Cannot connect to MQTT

Hi
I have already been connected yesterday with MQTT using MQTT Explorer but now don’t work anymore:

Why?
I’m in Italy and use the european Server

Thanks

Because you shared your password in public?

Because you haven’t got your Heltec WiFi LoRa v3 working yet?

But probably mostly because you’ve got TLS turned off.

Solved mqtts:// not present in host name.
Now I see $SYS.
