Let's Encrypt via Plesk
This guide shows how to issue a free Let's Encrypt SSL certificate for a domain in Plesk Obsidian and have it renewed automatically — directly in the panel, without the command line.
Prerequisites: Plesk must be installed and the domain set up in Plesk. The domain's A record must point to the server's IP. The Let's Encrypt extension must be active in Plesk (present by default).
Step 1: Navigate to the domain in Plesk
Step 2: Open Let's Encrypt
Step 3: Configure and issue the certificate
| Option | Recommendation |
|---|---|
| Email address | Your email address for notices about the certificate |
| Include domain | Enable for the main domain (e.g. your-domain.com) |
| Include www | Enable so the certificate also covers www.your-domain.com |
| Include webmail | Enable if webmail is accessible via this domain |
| Redirect HTTP to HTTPS | Enable — ensures all visitors are forwarded to HTTPS |
Click Get it free. Plesk issues the certificate, installs it, and automatically configures the HTTPS redirect.
Step 4: Verify automatic renewal
Plesk checks daily for certificates that are about to expire and renews them automatically. You can view the status under Tools & Settings → SSL/TLS Certificates.
If automatic renewal fails, Plesk sends an email notification to the address you provided. In that case, check whether the domain's A record is still pointing to the correct server.
