Make sure it matches the choice you’ve made as “Preferred domain” under Website&Domains->Hosting Settings
When the certificate is generated, you will see a banner on top of the page saying “Information: Let's Encrypt SSL certificate was successfully installed on the domain.com.
Step 2: Configure the Domain to use the Secure Certificate

Scroll down to the Security part.
Make sure the “SSL support” is checked and shows the Lets Encrypt certificate for the domain in the Certificate field.
If this is not the case:
Check “SSL support” and select the correct certificate if needed and scroll down to click OK.
Important: At this point you can test your web site pages and make sure they work in https.
