ReverseProxy Fixes, Nextcloud MariaDB Upgrade (#7)

* Working on getting Reverse Proxy certs to work.

* Upgrade mariadb to 10.6.

* Checking if anything has missed a check in.

* Let's Encrypt is working now after moving the location directive to the conf.d files. Unsure why nginx.conf is not passing it along, so added it to the examples too.
