How do I find the Root CA Certification file that was loaded for Ignition

If you do not have access to or cannot easily locate your Root CA Certificate required to be used by the MQTT Modules, you can download by using the Firefox browser.

Using Firefox, make a connection on port 8043 on the Ignition URL. 

You will be warned of a Potential Security Risk. Select Advanced and then select View Certificate.

The we browser will show each of the three certificates available. Select the Root CA tab and scroll down to find the download file link.

The file name when downloaded will be localhost.pem.
