NGINX Web SIte Configuration

I have a personal server with various apps running on in in Dockers. One of the Dockers is Swag (from LinuxServer-IO). I need help configuring it to get reverse proxies working, and re-directing SSL traffic. It uses LetsEncrypt.

I do own a domain name, and use no-ip.com to handle the DNS to my home's DHCP internet.

Additional help setting up various elements in Home Assistant would be great as well. Here is a list of what I need:

-Setup my NGINX site-confs to properly direct incoming traffic
-Make all incoming traffic use SSL
-Configure/check various reverse proxies
-Make sure my No-IP Managed DNS entries are properly routed
-Check router port forwarding is properly secured
-Setup a master password for SSL traffic

Home Assistant
-Integrate Smartthings Integration (broken now - was working)
-Currently have Alexa integration properly setup
-Configure and setup Harmony Hub integration to send individual commands to my deices. My current integration only executes activities.
-Create some sample automation scripts.
-Confirm backup and restore works

The tasks I need are fairly basic.

Thank you.
