How can I have my limit reset? I will request one cert for all my subdomains this time and back up my keys. =) I had no idea there was a rate limit to this.
If your situation is the same, then the answer is the same. The limit (as @serverco linked already) is 5 certs/domain/7 days. If you’ve already hit that limit, you’ll need to wait until 7 days after the first was issued. You can check your domain on crt.sh to see what certificates were issued and when.
