Nextcloud SSL Settings

I’ve installed nextcloud 16.04 on ubuntu 18.04.
How can I enable https and take certificate from rapid ssl.
I don’t want to use letsencrypt.

The usage of SSL is a web server related configuration and not a Nextcloud specific one. As usually aunt G. knows the answer.

Thanks for your answer. I’m not good at linux and I red a lot of articles about apache ssl but all of them explain about free ssl or local certificates. I want to use rapid ssl so how can I make that for nextcloud?

This will help you with any Certificate. Just put your rapid Cert path there.
