You're not the only one who has experienced the annoying "NET::ERR_CERT_AUTHORITY_INVALID" message when surfing the internet. When your web browser detects a problem with the SSL certificate of the website you're attempting to visit, this error message often occurs. Although at first, it can appear frightening, have no fear! The NET::ERR_CERT_AUTHORITY_INVALID problem will be explained, along with its causes and workable solutions, in this article.


A typical SSL-related issue that affects Google Chrome and other Chromium-based browsers like Microsoft Edge is NET::ERR_CERT_AUTHORITY_INVALID. This error indicates that the browser does not recognize the SSL certificate of the website you are attempting to access as legitimate. When there is a problem with the certificate, the browser prevents access to the website in order to safeguard your data from possible risks. SSL certificates are essential for safeguarding your connection to a website.


  • SSL certificates have an expiry date, and if the certificate for a website has passed that date, your browser will mark it as invalid.
  • Misconfiguration: This issue may be brought on by incorrect SSL certificate configuration on the server. This can be the result of setup or installation difficulties with the certificate.
  • Websites employing self-signed SSL certificates rather than those provided by reputable Certificate Authorities (CAs) may get this problem.
  • Domain Mismatch: The browser deems a website unsafe if the SSL certificate's domain does not match the domain of the page you are viewing.
  • Untrusted Certificate Authority: The browser will throw the NET::ERR_CERT_AUTHORITY_INVALID error if it does not know or trust the Certificate Authority that issued the SSL certificate.


Now that we are aware of the various reasons, let's investigate remedies to fix the NET::ERR_CERT_AUTHORITY_INVALID Error code. 

Method 1: Verify the system time and date

SSL certificate validation problems might be caused by an inaccurate system date and time. Check that the time and date settings on your device are correct before attempting to visit the website once again.

Method 2: Remove cookies and cache from the browser

Sometimes cookies and cached data might obstruct SSL certificate verification. To rule out this option, clear the cookies and cache in your browser.

Method 3: Update Your Browser

New SSL certificates may not be supported by out-of-date browser versions. To guarantee appropriate certificate validation, update your browser to the most recent version.

Method 4: Look for Firewall or Antivirus Interference

Antivirus software or firewall configurations may sometimes interfere with SSL certificate verification. Disable them momentarily and check to see whether the problem still occurs.

Method 5: Visit the website in anonymous mode

Try using private browsing or incognito mode to view the website. This will get around certain cache and cookie problems that could be the source of the error.

Method 6: Check the SSL certificate for the website

Manually check the website's SSL certificate. You may decide to go forward despite the mistake if you're certain it's true. Nevertheless, proceed with care.

Method 7: Contact the website owner or administrator.

Contact the website owner or administrator if you are continually running into the error on a reliable website to make sure they are aware of the problem.
