Many users are reporting the Chrome error code NET::ERR_CERT_AUTHORITY_INVALID along with message your connection is not private. If you are one of them who is facing this error and not able to access your favourite websites, you are reading the right tutorial. Here we will cover everything about this error including reasons and possible fixes. Let’s start with a brief introduction.



The Internet is one such thing which connects us with the world technically. Using the internet you can chat across continents, work on a project from anywhere, know what’s going in the world, and much more. Using a computer or a smartphone connected to internet, you can learn, work and shop within seconds. But, it is also one such thing, which the hackers can use to get your information, which they can later use to steal from you. We all use anti viruses and online security software applications to secure our computer from any such attacks. Also, website owners secure their websites in their own way. But what if, you yourself access a vulnerable website? What if, your own connection to a site is not private, or secure?


We all have come across such error at least once while browsing. Google Chrome usually shows this error when the website is not completely secure. But I have also seen Chrome showing the same error when it is the same website I accessed using the same browser last time which worked fine. Doesn’t matter the platform. Windows, Android or Mac, getting an error like NET::ERR_CERT_AUTHORITY_INVALID can be very frustrating. Don’t worry, in this guide, we will help you fix this error using some working methods, across all platforms. But first, let’s see what this error is?



The first thing to understand here is that it’s not really an error. It is just a warning message from your browser when it encounters a possible security breach. Google Chrome gives us this warning when we try to access a website whose issued certificates are not trusted by your device’s operating system. This happens when the server has generated its own certificates or credentials, which your browser can’t relay. At this point, your browser gives you a warning and lets you decide whether you want to visit an unsecured website or not. When the certificates from website and Chrome do not match, it thinks this as an unauthorized access by hackers. Hence, to keep your device and your personal information safe, Chrome displays this warning. In short, this error/warning is shown due to these reasons:

  • No Certificate issued by the third party site.
  • The Certificate of third party site is not updated.
  • Your browser and third part site connection is not secure.

This warning is displayed on our browser in following two different interfaces (Don’t worry, you can follow our methods in both interfaces).

  • Type one: This is normally seen in older versions of Chrome. Here you get the button “Proceed Anyway”.
  • Type two: This can be seen in the latest versions of Chrome. Here you get the button “Advanced”.

Step 2. In next step, the older versions will have the option to Add Exception, while the newer version browsers will show Proceed to site (unsafe) option. Select it, and your browser will proceed to that website.

3. Check the Antivirus or Firewall 

Antivirus also prevents your browser from viewing suspected websites and shows NET::ERR_CERT_AUTHORITY_INVALID warning on your browser. Users across the world use different antivirus software. But the procedure is same across every antivirus. You just need to turn off the SSL Scan or HTTP protection or HTTPS protection from your antivirus’ piracy settings, under settings.


4. Check Time and Date 

In most of the cases, the error could trigger due to wrong date and time. It prevents the Google Chrome browser from verifying the SSL certificates. Just update your date and time, and this will prevent from displaying the warning.

5. By Ignoring the SSL Certificates

Using this method, you can ignore the SSL connection error. This is not a permanent solution to your problem. But it will disappear the SSL errors from your chrome browser, until you choose to let them display again.

Step 1. Find the Google Chrome shortcut on your desktop, and right click on it. Select Properties.
