Use nginx as a proxy, following the example configuration. It's default configuration is to forward all traffic, except for PHP stuff, to Mattermost.
Add this so Nginx restarts when it gets a new certificate
cat <<<EOF > /etc/letsencrypt/renewal-hooks/deploy/nginx.sh
#!/bin/sh
systemctl restart nginx

chmod 0755 /etc/letsencrypt/renewal-hooks/deploy/nginx.sh
