Hello,
I am experiencing an SSL certificate issue that appears only in Firefox on the website:
Firefox blocks access with the following error:
SEC_ERROR_REVOKED_CERTIFICATE
The warning states that the certificate presented by www.flammagroup.com has been revoked.
However, the same website opens normally in Chrome and other browsers, which display the certificate as valid. cPanel also confirms that the certificate is correctly installed for both flammagroup.com and www.flammagroup.com.
Certificate details:
Common Name: *.flammagroup.com Subject Alternative Names: *.flammagroup.com, flammagroup.com Issuer: GoDaddy TLS Intermediate CA DV – R1v1 Valid from: 24 July 2026 Valid until: 7 February 2027 Serial number: 00:CA:B3:66:A5:75:82:BE:3F SHA-256 fingerprint: BC:56:25:D3:30:B9:85:72:AC:BD:0B:DF:3F:E7:1D:9C:BF:84:3F:DB:3C:98:B1:4E:B2:2B:59:F8:8E:78:99:08
The certificate currently served by the website is the same one installed in cPanel. An older expired Sectigo certificate is still stored on the server, but it is not installed on the website.
We have also requested a verification from GoDaddy to confirm whether this specific certificate serial number is active or revoked.
Could you please help us understand:
Why Firefox reports this certificate as revoked while other browsers accept it; Whether Firefox may be using a cached or incorrect OCSP/CRL response; Whether there is a way to clear or refresh the revocation information stored by Firefox; Whether this certificate serial number is included in any Firefox-specific revocation list.
The issue has also been reproduced outside the company network, so it does not appear to be caused by the local network, firewall or proxy.
Thank you for your assistance.
