Firefox says site is not secure

My domain is:

I ran this command: loaded the site on Firefox

It produced this output: Connection not secure (on my Mac, Safari displays a padlock; on iOS, Safari does not display a padlock; on my Mac, Chrome displays a padlock; on iOS, Chrome displays a triangle with an exclamation point in it;)

My web server is (include version): (Info from hosting service) Perl 5.24.1 PHP 5.2.17

The operating system my web server runs on is (include version): Debian GNU/Linux (doesn't give version)

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know): I don't know

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): No

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): I don't know. installed the certificate


Hi @ItsAMystery, welcome to the LE community forum :slight_smile:

The certificate is fine.
See: SSL Server Test: (Powered by Qualys SSL Labs)
The main problem is that not all content on the site is being secured.
Have a look at:
Test Results: - Why No Padlock?


Thank you for such a quick response and the site links, which I did not know about. I'm glad to hear that the certificate is fine. I will take a look at the results and see if I can figure out what to change on my site. This is my first go with a certificate, and I'm discovering just how much I don't know.


Update: I corrected the errors listed in "Why No Padlock" and I now have a padlock. Thank you very much!

My one remaining question is that Why No Padlock still shows an "SSL connection error":

The SSL certificate tests failed. Please be sure that you can connect to your site over SSL and try again.

but I have no trouble now connecting. What am I missing?

Thank you again.


Welcome to the Let's Encrypt Community :slightly_smiling_face:

Your certificate chain looks fine to me:

I still see a bunch of "mixed content" though:

Thanks, Griffin. I see now: there are two types of mixed content. I took care of the active ones, but there are still passive ones. (Again, all new territory for me.) I will go back and take a look.


All mixed content now taken care of. Thanks to Rudy and Griffin for their help and helpful links. I really appreciate it.
