🔐 Step 1: Obtain a Let’s Encrypt Certificate

1. Log in to the Plesk hosting control panel. You received access details when your hosting order was activated, for example: https://yourdomain.com:8443.

2. Go to Websites & Domains, click SSL Certificates, and select the Let’s Encrypt certificate for your domain.
   
   

3. In the form that opens, specify:

   • Email address to receive notifications from Let’s Encrypt.

   • Select the options:

     • Secure the domain name

     • Include a “www” subdomain

     • Secure webmail

     • Assign the certificate to the mail domain

4. Click Get it free.
   
   

Plesk will automatically generate and install an SSL certificate from Let’s Encrypt for your domain.

⚙️ Step 2: Select the Certificate in Hosting Settings

1. In Websites & Domains, click Hosting Settings for your domain.

2. In the Security section:

   • Check SSL/TLS support.

   • In the Certificate dropdown list, select the newly installed Let’s Encrypt certificate.

   • Click OK or Apply.
     
     

This ensures your website uses the new certificate for secure connections.

🔄 Step 3: Verification & Automatic Renewal

• The certificate is valid for 90 days.

• Plesk automatically renews it using the SSL It! extension.

• You will receive an email notification if there are any issues with renewal.

📌 Additional Tips
If you encounter issues issuing the certificate, make sure the domain is properly configured in DNS and accessible from the Internet.
