Firefox SEC_ERROR_UNKNOWN_ISSUER

ynzerr · September 28, 2023, 9:03pm

Now suddenly, all the websites hosted here that I’ve tested have this error on Firefox (including mine). I tried removing the certificate and installing a new one (from Google Trust to ZeroSSL), and still, the same problem persists. (Note: I also tried testing it on Firefox installed on a cloud server, and it still shows the same problem.)

is anyone else seeing this error or ?

Can you share your website’s URL?
This may be an SSL cache issue.

well i tried on a fresh install of firefox since chrome is my main browser. i don’t know if it needs some “use to” to be able to detect the certificate or something.

Hi, what URL are you trying to get to?

It loaded fast for me. No error. I am using Vivaldi Browser (Chrome based). I also tested on Firefox 117.0.1 (64-bit) on Windows 10 and it loaded your site without the error message. Maybe it’s a security setting or a browser plugin doing this?
