Subject: Persistent “Secure Connection Failed” after SSL certificate was re-issued – cannot clear cached certificate Hello Firefox Support, I am experiencing a persistent SSL certificate problem that only occurs in Firefox. Background

Domain: j3tourshongkong.com (and www.j3tourshongkong.com) The domain was recently moved to a redirect service (redirect.pizza) A new valid SSL certificate was issued by Let’s Encrypt via the redirect service The certificate is confirmed working by the certificate issuer and by redirect.pizza support

Current situation

HTTPS works correctly in Chrome, Edge, Safari, and on mobile browsers HTTPS works correctly on the same computer when using Chrome In Firefox (both normal and Private windows) I continue to receive “Secure Connection Failed / Not Secure”

What I have already tried

Cleared cookies and site data for the domain Cleared all recent history (including cache) Tested in a Private Window Restarted Firefox multiple times

None of these steps resolved the issue in my current Firefox profile. It appears Firefox has cached the previous (invalid) certificate state and is not refreshing it, even though a valid certificate is now being presented by the server. Could you please advise:

Is there a more thorough way to force Firefox to discard a cached SSL certificate for a specific domain? Or is this a known issue that requires a fix on the Firefox side?

I am happy to provide any additional technical details or screenshots if needed. Thank you for your help. Best regards, Jamie Lloyd

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
