There’s no way to “unlock” the rate limit. However, the particular limit you hit is a limit on certificates for an “exact set of domains”. You hit the limit for exactly
www.pokemap.uy on the same cert, but you could still get separate certs for each domain, or a cert for those two plus one more subdomain, etc.
In future you can use
--staging while you’re testing things out, as it has less strict limits.
