Enable SSL Listener

Learning Focus

By the end of this lesson you will know how to create an SSL listener on port 443 in OpenLiteSpeed.

Steps in WebAdmin

1. Navigate to Listeners → Add New Listener
2. Set:
   • Listener Name: HTTPS
   • Address: * (all interfaces)
   • Port: 443
   • Secure: Yes
3. Save

Verify

# Check if port 443 is now listening
sudo ss -tlnp | grep 443

If the listener does not start, check the error log:

tail -20 /usr/local/lsws/logs/error.log

Key Takeaways

• The SSL listener on port 443 is required for HTTPS traffic.
• Ensure no other service is using port 443 before enabling.
