Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Rate limit increases are for long term legitimate needs and aren’t provided to work around these kinds of situations. In any case, they take longer to be granted than the length of the rate limit, so it wouldn’t help you.
You can work around the problem by including an additional domain on the certificate, which will cause it to be categorized under a different rate limit bucket.
