How to get a free Let's Encrypt SSL certificate?

A free Let's Encrypt certificate is issued in the control panel and renews automatically.

Option 1. From the site settings

1. Open "WWW" -> "WWW domains" -> your site -> the "SSL" tab.
2. Click "Issue SSL".
3. Check the domains in the certificate (site aliases are added automatically), keep "Serve the site over HTTPS after issuance" checked and click "Issue".

Option 2. From the certificates section

1. Open "WWW" -> "SSL certificates".
2. Click "Issue".
3. Select the domain, the email for notifications and the validation method:
   • "HTTP-01" - the domain must already point to our server;
   • "DNS-01" - works through our DNS if the domain's NS are delegated to us; lets you issue a certificate before the site is switched and issue a wildcard *.domain ("Include the wildcard").
4. If needed, add "Additional names (SAN)" and click "Issue".

After issuance

• Turn on "Redirect to HTTPS" on the "SSL" or "Site" tab so that all visitors go to https.
• The certificate renews automatically. You do not need to do anything.
• If the certificate is issued but the site opens only over http, check that the "Serve over HTTPS" switch is on.

If the certificate is not issued

• The domain (and every name in the certificate, for example www) must point to our server's IP. If DNS is still updating, wait or use "DNS-01" validation.
• If the domain is on Cloudflare with proxying, use "DNS-01" (with our NS) or turn off proxying for a while.
