Nginx only serves 1 App

[Moshe Katz]

That last "# managed by Certbot" section looks wrong - it shouldn't be
using "if ($host = ...", since that's inefficient and there are much better
ways to do it.

I have a very similar server, so here are the config files I use for it. I
don't like pasting them into emails, so I made a GitHub Gist:
https://gist.github.com/kohenkatz/08a74d757e0695f4ec3dc34c44ea4369 (that
also means I can edit it later if it doesn't work for you).

Note that with this configuration you have to run Certbot in "certonly"
mode instead of nginx mode. However, that is very easy.
I have eight servers configured in this exact way (though most of them with
applications other than Seafile and Mattermost, but it doesn't matter).

Here is the certbot command I use:
sudo certbot certonly --webroot -w  /usr/share/nginx/html -d
domain-name-here.example.com
(If you changed the path for `.well-known` in the config files in my Gist,
you will also need to change it here.)

Let me know how this works for you.
