How to use own certificate in Caddy? How to show Caddy-related logs?

[cx0222]

My system is Ubuntu 22.04.5 LTS. I can use PDS normally, but I really want to use my own certificate. Therefore, I modified the /pds/caddy/etc/caddy/Caddyfile configuration file, deleted on_demand_tls, and added the crt and key files. However, PDS fails to start, and even when I enable logging, there are no Caddy-related errors.

The Caddyfile looks like:

{
	email admin@[MY_DOMAIN].cn
#	on_demand_tls {
#		ask http://localhost:3000/tls-check
#	}
}

*.[MY_DOMAIN], [MY_DOMAIN] {
#	tls {
#		on_demand
#	}
        tls /etc/ssl/certs/[MY_DOMAIN].crt /etc/ssl/private/[MY_DOMAIN].key
	reverse_proxy http://localhost:3000
}

1. Can I modify the Caddy configuration like this?
2. How can I view all of Caddy's logs?

Thank you so much!
