Let's Encrypt for Duckdns domain including other sites than Home Assistant

Hi, I want to run Nextcloud on the same domain, different port as I running Home Assistant. The question is how to use the same certificate from Let’s Encrypt even for the Nextcloud web. Is it possible please?

It depends on how you’re generating those certs really…

Are you using the Hass.io add-on, one of the Docker containers for LetsEncrypt, dehydrated, certbot, what?

Thanks for answer, I fixed it a couple days ago. I just pointed apache configs on the certs that are maintained by DuckDns in Hassio.
