There isn’t a rate limit that lasts 5-7 days, but there is a limit of 5 duplicate certificates per 7 days. Is that what you ran into?
If so, you can circumvent it by requesting a new certificate for a different set of domains. For example, if the cert you’re having trouble with is for
example.com, you could request one for
www.example.com. Or if it’s for
www.example.com, you could add another subdomain e.g.
extra.example.com and then request a single cert covering all three.
There is also a limit of 50 certificates per registered domain per week, which cannot be circumvented in this manner. If you hit that one, you’ll just have to wait it out (or if you need a cert urgently, get one from another CA).
