Nginx only serves 1 App

[Moshe Katz]

Somehow we all missed that - of course you can't run `http2` on port 80 and
have it work since `http2` requires SSL.
With that configuration, you would have been able to get to the chat
subdomain only by going to `https:// chat.mydomain .com:80/` - notice that
it is https but is forced back to port 80. (I purposely added spaces to
prevent that from being a link in many mail clients.)

To answer the question about LetsEncrypt renewal, you need to leave nginx
running in order for it to work since it still relies on nginx to serve the
`.well-known` files that make the domain verification work. If you would
stop nginx, you would be unable to run the validation.

The one thing that you do need to do is make sure that LetsEncrypt knows to
reload nginx when a certificate changes so that nginx can see the new
certificate file.
If you are on a system that uses SystemD, this is what you need to do:

Create a shell script in `/etc/letsencrypt/renewal-hooks/deploy` with the
following contents:

#!/bin/bash
/bin/systemctl reload nginx.service

Make sure to set it as executable, and then Certbot will run it
automatically for every renewal.

Alternatively, you can go into each file in `/etc/letsencrypt/renewal/*`
and add the following line in the `[renewalparams]` section:

deploy_hook = /bin/systemctl reload nginx

Of course, that means you need to modify the renewal file for each domain
separately.
