Should Caddy and Traefik Replace Certbot?

This is a most excellent place for technology news and articles.
Can you elaborate on this reliability issue?
Certbot is supposed to automatically renew certificates. It doesn't do that reliably in my experience.
We use it on non-critical systems and every few months I need to go in and fix things... that never happens with traditional certificates - those are setup and forget.
As for the exact problems, I don't think we've ever had the same problem twice. It's always a once off thing but it's still an hour of wasted time each and every time. If it happened on a proper production system it'd be a lot more than an hour, since whatever change is made would need a full gamut of testing / reporting / etc.
