Specialists on server told that they fixed the problem with Let’s encrypt module, but they told me that Let’s Encrypt banned my domain up to 7 days. I asked them to solve the problem, they say they don’t have access to Let’s Encrypt. Maybe you can help me?
However, the main limit that takes 7 days to reset is when you issue many identical certificates. Then you will have to wait a week in order to get new ones. This does not appear to have happened for your domain:
If you make too many unsuccessful attempts to obtain a certificate, there is also a limit that will block new attempts. However, this limit times out after only 1 hour, not 7 days. Thus, it should be possible to try again just by waiting for 1 hour.
Seconding what @schoen said here (thanks!) it looks like previously you were hitting the hourly failed authorization limit.
Was your host able to figure things out? I see that at 2017-11-09T18:24 UTC there was a successful certificate issuance for a cert covering portosound.com and www.portosound.com.
