Where can I get the certificate for MQTT server?


I am not sure where can I get *ca.pem certificate file for the MQTT server in groov EPIC. I haven’t activate my Ignition yet.
I search for a few tutorials on youtube to enable MQTT service in the Ignition trial version. But I am stuck with the certificate problem.

Do you have an IT department?
They are the ones to see. It needs to match the MQTT server that you are connecting with, so who ever set that up will be able to help you.

So we have to create own Chariot MQTT server to obtain the certificate right?
(ps: I thought there is a server in EPIC ignition edge)
If we use server other than Chariot, we have to select MQTT Distributor for server type?
