My hosting company tried twice to install a LetsEncrypt certificate and received the error that the rate limit had exceeded 20 attempts. I see in a post in July that this could be a Plesk problem. Does anyone have any further information on this that I can pass on to them?
This is their description of the problem:
While checking we could see that a Lets Encrypt certificate was installed for "zoowoods.ca" but the certificate was not been recognized, we identified that the Lets Encrypt certificate was not selected for the domain under Hosting Settings but during the investigation, was tried to install a new Lets Encrypt certificate, the current certificate was removed and the following error was displayed.
The "Certificates per Registered Domain" rate limit has been exceeded for zoowoods.ca. Let's Encrypt allows no more than 20 certificates to be issued per registered domain, per week.
