How can I use Traefik to issue SSL for ERPNext that has been manually installed (not dockerized)?

Traefik Traefik v2

The operating system my web server runs on is (include version):
Ubuntu 24.04.2 LTS

My hosting provider, if applicable, is:
Hostinger

We have another application, Rocket.Chat , running on ports 80 and 443 , using Traefik for SSL. However, I don’t want to use Traefik for ERPNext SSL. Is there a way to configure Nginx separately to handle SSL for ERPNext OR use Traefik as reverse proxy for it?

If you configure Traefik to use LetsEncrypt, then it will create TLS certs for each domain configured. Even if the target service is outside of Docker. Simple Traefik external example.
