Several tested fixes for the net::err_cert_authority_invalid error message are covered in this article. Let’s investigate its common causes first.

The Meaning of the Error Code NET::ERR_CERT_AUTHORITY_INVALID

Browsers that might be unable to check SSL certificates for a website may also display the security-related message NET::ERR_CERT_AUTHORITY_INVALID. If users proceed despite this warning, they might mistakenly assume that the website obtained its SSL certificate from an unreliable Certificate Authority (CA), potentially exposing user data and critical information. While unsecured network connections, browser caches, and expired SSL certificates are commonly implicated, we cannot deny that they are among the most notorious culprits.

The NET::ERR_CERT_AUTHORITY_INVALID Error’s Cause

NET::ERR_CERT_AUTHORITY_ is the following SSL and browser-related problems that may cause an INVALID error:

Expired SSL certificates: Until the certificate is renewed, a browser will typically flag an expired certificate as invalid.
Self-signed certificates: These SSL certificates do not have the third-party verification browsers authorities need and are not prepared by a Certificate Authority (CA).
Inaccurate time and date: An outdated operation system may have a most dependable and precise time and date setting, under which it might simply treat a valid certificate as faulty only because it has expired.
Untrusted Certificate Authority: The SSL certificate for your website was obtained from an unidentified CA that isn’t included in the trusted certification authority list for browsers.
SSL state or outdated browser cache: For quicker connections, browsers save cached certificates, however, a corrupted or outdated cache might cause a discrepancy with the real certificate.
Interference from virtual private networks VPNs: Certain security programs, such as firewalls and antivirus software, can cause problems with the SSL handshake procedure and cause browser warnings.
Conflicting browser extensions: When a browser tries to check certificate information, an extension may mistakenly alter or prevent it.

How Various Browsers Display the NET::ERR_CERT_AUTHORITY_INVALID Error
