How to add to HTTPS back ends?

Traefik Traefik v2 (latest)
1

I want to switch my back end web apps over to HTTPS using their built in self signed certificates which are in a java keystore. Can anyone suggest changes to my config files or a help article for this situation?

Just getting into this and I have Traefik v2 set up to the point where I can use Let's Encrypt for the public side and regular HTTP for the back end connections. Finding it a little hard on how to search for this change on the back end connection but this is my functioning config at the moment. I commented out letsencrypt as this test machine isn't on the public web to do the challenge.
