SSL错误：安全连接失败

Question

I purchased a SSL certificate that will expire in 2019 , Then I installed it and now it's doing well on Chrome and showing green Padlock.

But on Mozilla Firefox, I get an error:

Secure Connection Failed

An error occurred during a connection. Peer’s Certificate has been revoked.
Error code: SEC_ERROR_REVOKED_CERTIFICATE

I searched for an answer and viewed some questions about it here , But didn't find a solution.

What is the problem and how to fix it?

How is it possible to be secured on a browser and not on another?

The report from SSLLabs clearly shows that the certificate was revoked, thus Firefox is complaining correctly:

Revocation status   Revoked   INSECURE

How is it possible to be secured on a browser and not on another?

Browser check in different ways for revocation or might check not at all. The old was was to use CRL which did not scale. The modern way is to use OCSP which requires the OCSP server of the CA to be always reachable and also might slow down the connection establishment unless OCSP stapling is used. Therefore Chrome uses CRLSets which contains only the revoked certificates Google considers relevant.

In your specific case the certificate is revoked. Firefox probably used OCSP to check for it and successfully detected the revocation. Chrome used CRLSets and since your site was not deemed important enough Google did not include the revocation into the CRLSets and thus the revocation was not detected.

I was lifting Wordpress backup and got this line "Secure Connection Failed". These errors were due to plugins requiring SSL certificates such as Google analytics. after removing the plug-ins, everything worked.
