Well the reason I was trying to redirect to Google is to check whether I was able to access a site through Cloudflare using my own domain. Which apparently I can, but I wasn’t doing it right.
The issue I am having is, that I would like to be able to access my Plex Container running on Unraid (And other containers in the future) over the internet using a reverse proxy.
So I have set up my portforwarding, duckdns and letsencrypt and I can access the letsencrypt container locally using 192.168.2.10:443 but the plex.mydomain.com is not working. It just times out and I am not sure what the problem is.
