Re-install certificates after server crash

Another problem might be that I'm using a dynamic DNS provider that hits the rate limit and thus cannot easily create a new certificate or can I?

As I understand it, newly issued certificates are considered renewals for rate limiting purposes if they contain the exact same set of FQDNs (domains and subdomains) as an existing certificate - it should not matter whether you use the renew command or not.
