The error “NET::ERR_CERT_AUTHORITY_INVALID” that you’re encountering typically occurs when there’s a problem with the SSL certificate of a website, specifically that your web browser doesn’t trust the certificate authority (Cisn’tsuing the SSL certificate.
Things to remember:
Before attempting to fix the NET::ERR_CERT_AUTHORITY_INVALID error, it’s crucial to approach the issue methodically. To effectively address the NET::ERR_CERT_AUTHORITY_INVALID error, start by verifying the SSL/TLS certificate details and identifying the root cause of the error, such as a misconfiguration or an expired certificate. Always back up existing configurations before making changes and adequately install all intermediate certificates. After updating certificates or configurations, test the setup using tools like SSL LabLabs’L Test and consult your hosting service’s documentation or support if needed. It informs users about changes that might affect their experience and ensures that security software is configured to trust the new certificates.

What Is the NET::ERR_CERT_AUTHORITY_INVALID Error?
The “NE”:: ERR_CERT_AUTHORITY_INVALID” e “is a message that commonly appears in web browsers when there is a problem with a website’s SSL/TLS certificate. This error indicates that the browser does not trust the certificate authority (CA) that issued the SSL certificate, which prevents the browser from establishing a secure connection to the website.
Here are some critical aspects of this error:
- Certificate Authority Trust Issues: The error typically occurs because the browser does not recognize or trust the certificate authority that issued the website’s L certificate. This could be due to the CA needing to be discovered, the certificate being self-signed, or the certificate coming from an authority not included in the brobrowser’sst of trusted CAs.
- Self-signed Certificates: Websites using self-signed certificates are common triggers for this error, especially in development environments where a recognized CA has not issued the certificate.
- Improper Certificate Configuration: Sometimes, even if the certificate is from a trusted authority, it may need to be appropriately configured on the server. This can include issues like missing intermediate certificates necessary to complete the trust chain back to a recognized root CA certificate.
- Expired Certificates: This error can occur if the SSL certificate has expired or there are issues with the certificate’s sliding period due to incorrect system dates.
- Security Software Interference: Some antivirus or network inspection tools can intercept SSL certificates and replace them with their own for scanning purposes, which the browser may not trust.
How It Affects Users and Security
When this error occurs, it warns users of a potential security risk when using the website. Suppose the certificate is not from a trusted authority. In that case, it could be a man-in-the-middle attack, where an attacker presents a fake certificate to intercept or manipulate the secure communication.
What Are the NET::ERR_CERT_AUTHORITY_INVALID Error Variations?
The “NE”:: ERR_CERT_AUTHORITY_INVALID” e “or primarily indicates a trust issue with the SSL/TLS cercertificate’ssuing authority, but there are variations of this error and other related errors that you might encounter depending on the specific problem with the certificate or its chain. Here are some common associated variations and mistakes you might see in browsers:
- NET::ERR_CERT_COMMON_NAME_INVALID: This error occurs when the common name (CN) or subject alternative name (SAN) listed in the certificate does not match the domain name the user is trying to visit. This is a hostname mismatch error.
- NET::ERR_CERT_DATE_INVALID: This error appears when the SSL certificate is expired, not yet valid, or if the comcomputer’ste and time settings are incorrect, making the browser believe that the cercertificate’slidity period is erroneous.
- NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM: This error is triggered when the SSL certificate uses a cryptographic signature algorithm that is considered insecure or deprecated, such as SHA-1.
- NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED: This error occurs when the certificate is not logged in a public Certificate Transparency log, which is now a requirement for all trusted certificates under certain conditions.
- NET::ERR_CERT_REVOKED: This error indicates that the issuing Certificate Authority has revoked the SSL certificate. Revocation can happen for several reasons, including security breaches or compromised keys.
- NET::ERR_CERT_INVALID: This general error indicates that something wrong with the certificate prevents it from being used. This could be due to parsing errors, incorrect formats, or other issues that invalidate the certificate.
What Causes the NET::ERR_CERT_AUTHORITY_INVALID Error
It is a common issue that browsers display when they encounter a problem with a website/TLS certificate, specifically regarding the certificate authority (CA) that issued it. Here are the primary causes of this error:
- Untrusted Certificate Authority: The error most frequently appears because the certificate was issued by a CA that is not trusted by the browser. This may occur if the certificate needs to be listed in the browser’s trusted CA list or was self-signed or issued by a CA.
- The certificate is not installed correctly: If the CA’CA’stermediate certificates are not installed correctly on the server, the browser may be unable to trace a trust path from the certificate back to a trusted root CA.
- Expired Certificate: Sometimes, the certificate has expired, and the error is displayed because the browser does not trust outdated certificates.
- Mismatched Certificate Details: Browsers will show this error if the certificate was issued to a different domain name (or a subdomain).
- Security software interference: Sometimes, antivirus or network inspection tools intercept secure connections and present their own certificates to scan for malware. If these intermediary certificates are not trusted, browsers will flag them.
- Network issues: Misconfigurations or attacks on your network (like DNS spoofing or Man-in-the-Middle attacks) might cause your connection to be routed through servers with incorrect or untrustworthy certificates.
