Install NextCloud on Ubuntu 16.04 nginx with existing home web page

I would like to know how I can add NextCloud to my current nginx web page http & https with LetsEncrypt already installed without affecting normal web page users.

I actually just literally finished a working install of Nextcloud/Onlyoffice on a single Ubuntu 16.04 server, using Nginx, It’s pretty straight forward as long as you get your virtualhost config files right… thats what took me the longest.

Althought my install using two different domain names for the Nextcloud and OnlyOffice sites, I dont see why having another virtualhost site on it would be a problem.

Also the install I done was a native install, didn’t use container for either virtualhost.
