TLS setup on MQTT modules ver. 4.0.29

Ignition
1

I am currently trying to setup TLS for my MQTT network, utilizing MQTT Distributor and Engine version 4.0.29.

I have never done this before so I followed the instructions from "Implementing MQTT in Ignition: Video 11" but I noticed that the configuration interfaces are different between the version used in the video and mine.

For my version, I only see options to upload files within config > MQTT Engine Settings > Server > TLS.

Where do I upload my Java KeyStore file & enter my password?
Where do I upload my my certificate file?

MQTT Distributor shares the TLS certificate of the Ignition webserver. If you configure TLS for Ignition, that certificate will also front 8883/tcp for mqtts. The config section for Engine is for setting up mutual TLS for authentication to a remote MQTT broker.
