Hi Florian,

Thanks for your reply.

I can connect to HiveMQ cloud using MQTTnet library for Visual Studio.  
I didn’t need to refer to any certificates to do this.  
So, is simply connecting to HiveMQ without any certificates involved a secure (and encrypted?) connection on it’s own, or do I still need to use other certificates?

In my software MQTT connection window, there are the following inputs:

- Broker address
- Broker port
- Client ID
- Username
- Password
- UseTLS (tick box)
- MQTT Version (3.1, 3.1.1 & 5.0)

Do I also need to include a “browse for certificate (pem?) file” - just in case?

Thank you
