Installing a free Let's Encrypt SSL certificate in CyberPanel

CyberPanel features a built-in integration with the Let's Encrypt Certificate Authority. This allows you to migrate your website to the secure HTTPS protocol in just a few minutes without the need to manually edit OpenLiteSpeed configuration files.

• Official SSL documentation →

Before issuing a certificate, ensure that your domain (and the www subdomain) points to your server's IP address (via an A-record in DNS). Otherwise, the Let's Encrypt validation process will fail.

Step 1. Access SSL management

To start the certificate issuance process, follow these steps:

1. In the left-hand sidebar, navigate to SSL → Manage SSL.
2. Select the domain you want to secure from the Select Website dropdown menu.

Step 2. Issue the certificate

Once the domain is selected, the system will automatically prepare for installation:

1. Hit the Issue SSL button.
2. Wait for the process to complete. The panel will verify domain ownership and automatically apply the certificate files to your OpenLiteSpeed configuration.

The Let's Encrypt certificate issuance process

CyberPanel automatically sets up a cron job to handle certificate renewals. You don't need to renew them manually—the panel will take care of it 30 days before they expire.

Setting up HTTPS redirection

To ensure all visitors use a secure connection, you should configure a redirect:

1. Navigate to Websites → List Websites.
2. Click Manage next to the relevant website.
3. Scroll down to the Configurations block and select Rewrite Rules.
4. Choose the Force HTTP to HTTPS template from the dropdown menu and click Save Rewrite Rules.

Troubleshooting

If you encounter an SSL Message: Failed error during issuance, check the following:

• DNS Records: Confirm that the domain is fully propagated and pointing to the correct IP.
• Firewall: Ensure that ports 80 and 443 are open in the Security → Firewall section.
