Errors can come from the certificate itself, server configuration, or client-side issues. Identifying the source is essential to apply the right fix.

- Test multiple browsers: If error only appears in one browser, it might be a local issue.
Solutions

- Install complete chain: Add missing intermediate certificates in server configuration.
- Check domain: Ensure certificate covers www and non-www if you use both.
Frequently Asked Questions
Why do some users see the error and not others?
Different browsers and systems have different certificate stores. An incomplete chain may work on some but not all.
Can the error come from the visitor?
Yes, incorrect system clock, antivirus intercepting SSL, or missing root certificate can cause client-side errors.
How does MoniTao help with SSL errors?
MoniTao checks your SSL certificate, its expiration date, and chain validity. You're alerted before visitors see errors.
Is a free certificate less reliable?
No, Let's Encrypt is recognized by all modern browsers. The difference is in validation (DV vs OV/EV), not technical reliability.
