ERR_CERT_REVOKED
ERR_CERT_REVOKED Error
What This Error Means
The ERR_CERT_REVOKED error indicates that the website's SSL certificate has been explicitly revoked by the Certificate Authority (CA) that issued it. This is a severe security warning, meaning the certificate is no longer trusted even if it hasn't expired yet. Revocation usually happens when the certificate's private key is compromised or the certificate was issued improperly.
Common Causes
- The website owner requested revocation due to a security breach (e.g., stolen private key).
- The Certificate Authority discovered the certificate was issued to the wrong entity.
- The certificate violated CA policies or industry standards.
- The domain ownership changed, and the previous owner revoked the old certificate.
- Malware or antivirus software on the client machine interfering with the certificate chain.
How to Fix It (For Users)
- 1 Do not proceed to the website. A revoked certificate is a strong indicator of a security risk.
- 2 Contact the website owner through other channels to inform them of the issue.
- 3 Check if your antivirus software is scanning encrypted connections and causing false positives.
- 4 Ensure your operating system's Certificate Revocation List (CRL) cache is up to date.
For Site Owners / Developers
- Immediately contact your Certificate Authority to understand why the certificate was revoked.
- Generate a new Certificate Signing Request (CSR) and reissue the certificate.
- Install the new certificate on your web server.
- Investigate your server for security breaches if you did not request the revocation yourself.
- Ensure OCSP stapling is configured correctly to serve valid revocation status.
When It Is NOT Your Fault
If the Certificate Authority revoked the certificate in error or due to a mass revocation event.
