What are anyone thoughts on setting up CrowdSec at Coolify's Traefik proxy?

I'm not very familiar with Traefik and ended up reading CrowdSec and Trafic docs when setting up.

Managed to setup CrowdSec on a Coolify instance on Digital Ocean but it requires more fiddling (SSH and sudo nano) than I liked. It was a good learning experience but the resulting droplet instance is not something I'm confident in hosting anything important.

I have also restricted unneeded ports on DO's firewall and configured Ubuntu Pro. I wonder what else I missed?

I might rebuild the server following this guide as CrowdSec seems to be throwing errors/warning during apt update / apt upgrade. Plus this guide feels more complete.
