I am trying to create a new subdomain and when I went to try and create a new Let's Encrypt certificate, I hit a rate limit error message.
I believe I have now fixed the environment which was preventing the issuance of a new SSL Lets encrypt certificate, but how long do they rate limit you for ? (Meaning when can I try again ? )
I followed the link to their documentation, but it does not specify how long I will be not able to get the SSL certificate , because without it, I am a sitting duck in terms of of NOT being able to even get into the WordPress install and do what needs to be done.
thanks.

If you’re trying to issue a certificate with the exact same set of domain names, you’re limited to 5 attempts per week.
There is a Failed Validation limit of 5 failures per account, per hostname, per hour.
