Understanding SSL Certificate Issues
SSL certificates create a secure connection between your site and visitors. Squarespace provides these free for any domain pointed at your site, but you might still see warnings like "Your connection is not private" or "Your connection is not secure."...
Before You Start Troubleshooting
Give it time
Newly connected or adjusted domains need up to 48 hours to fully connect and generate their SSL certificate. If you've just made changes, wait this out before panicking.
Check where your domain points
SSL certificates on Squarespace only work for domains pointing directly to a Squarespace site. If your domain points somewhere else, you'll need to get SSL from wherever it's actually hosted.
Understand DNSSEC vs SSL
DNSSEC adds extra security to your domain settings (separate from SSL). Squarespace provides DNSSEC automatically, but mixing it with third-party DNSSEC services can sometimes interfere with SSL setup.
Common SSL Error Messages and How to Fix Them
"Your connection is not private/secure"
This error usually means temporary issues or setup problems. Here's what to do:...
"SSL Certificates Unavailable"
This means Squarespace can't generate an SSL certificate for your domain. Try these fixes:...
Quick tip: Switch to a current, supported browser. Older browsers sometimes don't recognise Let's Encrypt certificates (which Squarespace uses)...
Checking for Mixed Content
Mixed content happens when your secure site (HTTPS) tries to load something over an insecure connection (HTTP). This triggers security warnings...
When to Contact Support
If you've waited 48 hours, checked all your settings, and still see SSL errors, contact Squarespace support. They can check server-side issues that aren't visible from your end...
Quick Reference: Jargon Explained

SSL issues can be frustrating, but they're usually straightforward to fix once you know what to look for. Most problems resolve themselves within 48 hours of connecting a domain. If yours doesn't, work through these steps systematically and don't hesitate to get help if you're stuck.
