Installed Cert, can't connect to https

I’m running a node + express server on ubuntu 14.04. I was able to install and set up the auto renew cert yesterday with help from Schoen (thanks for the fast response), but now I’m stuck trying to actually apply it to my website. I’m wondering if this is something that was supposed to happen automatically, or if there are extra steps that I need to follow that are outlined somewhere specific for my node/express server.

Thanks!

If you used Certbot, there is no automatic installation available yet for anything but Apache (and experimentally nginx). For other webservers, you need to follow the webserver’s own instructions for how to install a certificate.
