Rocket.Chat stopped working over HTTPS

Rocket.Chat 0.71.1 (Ubuntu 18.04, snap) stopped working over HTTPS.
You can connect over HTTP on port 3000, but not HTTPS on a domain name. Settings no has not changed, the processes all work.
What to do?
How to understand whether the redirect from port 443 to port 3000 works on the host?

What are you using to handle your ssl termination? The built in caddy? If so please check status and get logs to see what’s happening

Customized in accordance with the documentation on the site. Used by caddy.
