I think my IP address is blocked

It looks like our ip address is blocked by you, something similar to the following issue, can you please unblock it:

My domain is: https://halifaxcranehire.com.au/

I ran this command: Create a certificate via Plesk

It produced this output: requests.exceptions.SSLError: HTTPSConnectionPool(host='acme-v02.api.letsencrypt.org', port=443): Max retries exceeded with url: /directory (Caused by SSLError(SSLError("bad handshake: SysCallError(-1, 'Unexpected EOF')")))

My web server is (include version): Plesk

The operating system my web server runs on is (include version): Ubuntu

My hosting provider, if applicable, is: 203.18.250.10

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Plesk

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

I do find interesting the DNS SOA and NS Records are without Domain Names just IP Addresses
