NET::ERR_CERT_AUTHORITY_INVALID error, What is the NET::ERR_CERT_AUTHORITY_INVALID Errror, How To Fix the NET::ERR_CERT_AUTHORITY_INVALID Error

NET::ERR_CERT_AUTHORITY_INVALID error can be received by users from time to time, even if an SSL certificate is already installed on a website. Although your connection is not secure error can be scary, there is no need to panic.

Simply put, a privacy certificate error means that your browser does not recognize the validity of the certificate on a website. Browsers show such errors to users to ensure safe internet browsing. Thanks to these alerts, you know whether you are accessing a secure website and you will be conscious. However, if you are the owner of the website where the error is displayed, there are many different solutions.

In this article as Sign In Up Blog; We explained what the NET::ERR_CERT_AUTHORITY_INVALID error means, how it is displayed in which browser and possible causes. In addition, the solution to the problem is also in our article. Without further ado, let’s go ahead and explain the nature and solution of this goddamn problem.

Looking at the content of the error in question, the reason is almost understandable. Your browser will give you a warning that the website you want to access cannot verify the validity of the SSL certificate. It is not possible to get this error if the website owners have not installed a suitable SSL certificate for the site or if they use HTTP instead of HTTPS in their domains.

What is the NET::ERR_CERT_AUTHORITY_INVALID Errror?

However, there are three main reasons for this situation, which is often referred to as a privacy certificate error. To list these reasons in substance:

Using a Self-Signed Certificate: Using a self-signed SSL certificate can cost less, but browsers sometimes fail to verify the validity of these certificates. Therefore, users who want to access your website may encounter this error. The fact that browsers give the said error affects many users negatively. This causes the number of visitors to your website to decrease.

SSL Certificate Expiration: SSL certificates may expire in accordance with security measures. The validity periods of certificates vary and it may be necessary to renew an expired certificate manually or automatically. If an expired certificate is installed on your website, this error can be shown to users in their browsers. Users who want to access your website may receive this warning due to certificate validity issues.

Certificate Not From a Trusted Organization: As with self-signed SSL certificates, this error can occur if browsers cannot verify the source from which the certificate was created.

Every time Internet users enter a website with an SSL certificate, their browser will want to authenticate. If any error occurs during this validation process, the same warning will still be displayed.

In many cases, internet browsers block users from accessing the website for their safety if there is any error. During this blocking process, a warning is usually received as “Your connection is not private”. This is a serious error for website owners, as it can significantly reduce visits again.

In some cases, NET::ERR_CERT_AUTHORITY_INVALID error may be encountered due to local configuration settings.

NET::ERR_CERT_AUTHORITY_INVALID Error Types

The way this error is displayed may differ depending on the internet browser used. In addition, the operating system and certificate configuration can also play an important role in the appearance of the error with different expressions.

So let’s take a look at the most famous NET::ERR_CERT_AUTHORITY_INVALID errors that can vary from browser to browser.

1. NET::ERR_CERT_AUTHORITY_INVALID Google Chrome

When you encounter NET::ERR_CERT_AUTHORITY_INVALID Google Chrome in Chrome, Chrome will instantly give you the “Your connection is not secure error”. Because, like other browsers, if Chrome cannot verify the validity of the certificate on the website, it cannot ensure that your data is safe.

When you click on the “Advanced” option on the page where you received the error, you will receive a warning that you can continue to the relevant website at your own risk.

In common versions of this error in Chrome, you are likely to view the following codes.

  • NET::ERR_CERT_AUTHORITY_INVALID
  • NET::ERR_CERT_COMMON_NAME_INVALID
  • NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM
  • NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
  • NET::ERR_CERT_DATE_INVALID
  • SSL Certificate Error

In such cases, Chrome determines the content of the certificate-related error and allows you to access the website if you want. However, it does not hesitate to give a warning.

Google Chrome Certificate Issue

One of the problems frequently encountered by Chrome users is Google certificate (SSL) errors. There are more than 170 million SSL-certified websites on the internet today, and this number is expected to grow as more search engines and consumers choose these sites. SSL certificate makes your site look more reliable. An SSL bug does the opposite. If customers no longer trust you, you can expect them to look to a competitor they can truly trust. In this topic, we will discuss what Google certificate issue means and what can cause it. Next, we’ll review the different steps you can take to resolve the error and get your site up and running again.

First of all, let’s start with the question of what is a Google certificate error. A Google certificate issue occurs when the Chrome web browser cannot verify the SSL certificate installed on a site. Instead of connecting users to your website, the browser displays an error message, warning users that the site may be unsafe.

An SSL certificate is a standard security technology used to encrypt information between a visitor’s browser and your website. Visitors feel more secure on SSL-encrypted sites as it helps keep sensitive information such as passwords and payment information secure. You can identify sites that are encrypted with HTTPS in their URLs and the padlock icon in the address bar.

Unencrypted sites can hit their traffic or conversion rate. These sites are not only marked as “Not safe” in Google Chrome, but are avoided by 85% of online shoppers.

Types of Google Chrome Certificate Error

Let’s say you choose a plan that includes an SSL certificate or you install a certificate on your site. Then you open Google Chrome and try to visit a page on your site, and instead of loading the page, you get the “ERR_SSL_PROTOCOL_ERROR” message. This is a type of SSL certificate error. You may receive this and many other types of certificate error messages. Let’s take a look at the most common types of certificate errors.

1. SSL Certificate Not Trusted Error (NET::ERR_CERT_AUTHORITY_INVALID Google Chrome Error)

This error indicates that the SSL certificate was signed or certified by a company that the browser does not trust. This means that the company known as the certificate authority is not in the browser’s built-in list of trusted certificate providers, or the certificate was issued by the server. Server-issued certificates are often called self-signed certificates.

2. Name Mismatch Error (NET ERR CERT COMMON NAME INVALID Error)

This error indicates that the domain name in the SSL certificate does not match the URL typed into the browser. Something as simple as “www” can cause this message. Let ‘s say the certificate is registered for http://www.yourwebsite.com and you type https://yourwebsite.com. Then you get an SSL certificate name error.

3. Mixed Content Error

This error indicates that a secure page (loaded with HTTPS in the address bar) contains an item loaded from an unsafe page (loaded with HTTP in the address bar). Even if a page contains only one unsafe file (usually an image, iframe, Flash animation, or JavaScript snippet), your browser will display an error message instead of loading the page.

4. Expired SSL Certificate Error (NET ERR CERT DATE INVALID Google Chrome Error)

This error occurs when the site’s SSL certificate has expired. According to industry standards, the lifetime of SSL certificates cannot exceed 398 days. This means that every website must renew or replace its SSL certificate at least every two years. Otherwise, when you try to load your site, you will see an error similar to: NET::ERR_CERT_DATE_INVALID

5. SSL Certificate Revoked Error (NET::ERR_CERT_REVOKED)

This error indicates that the CA revoked or revoked the SSL certificate of the website. This could be because the website obtained the certificate with the wrong credentials (accidentally or on purpose), the key was compromised, or the wrong key was issued.

6. General SSL Protocol Error (ERR_SSL_PROTOCOL_ERROR)

This error is particularly difficult to resolve because there are multiple possible causes, including:

  • A malformed SSL certificate that the browser could not parse.
  • A certificate not properly installed on the server.
  • Incorrect, unverified, or lack of digital signature.
  • Using an old encryption algorithm.
  • A firewall or other security software interfering with SSL protection.
  • A problem in the certificate’s trust chain may have affected the array of certificates that make up your site’s SSL encryption.

In these cases, you’ll see a generic SSL message like this: ERR_SSL_PROTOCOL_ERROR

2. Mozilla Firefox NET::ERR_CERT_AUTHORITY_INVALID

Firefox doesn’t waste time warning you that you may have encountered a potential security risk. Firefox also behaves more professionally than Chrome in its process of explaining possible reasons why you’re getting this error and warning you not to panic.

Although Firefox often does not give error codes, sometimes the following error codes may appear when you experience this problem:

  • SEC_ERROR_UNKNOWN_ISSUER
  • SSL_ERROR_RX_MALFORMED_HANDSHAK
  • MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE
  • SEC_ERROR_REUSED_ISSUER_AND_SERIAL

If Firefox gives you one of these error codes, doing a little research on the internet is enough to solve the problem. Firefox notifies you of the source of the error with these specific codes. Therefore, the solution to the problem is hidden in the error codes.

3. Microsoft Edge NET::ERR_CERT_AUTHORITY_INVALID

Edge’s error screens are almost identical to Chrome’s. However, the following codes can also appear in Edge:

  • DLG_FLAGS_SEC_CERTDATE_INVALID
  • DLG_FLAGS_INVALID_CA
  • DLG_FLAGS_SEC_CERT_CN_INVALID
  • NET::ERR_CERT_COMMON_NAME_INVALID
  • ERROR CODE: 0

As you can see, error messages give information about where the problem originates, just like in Chrome. So the NET::ERR_CERT_AUTHORITY_INVALID error occurs in Edge with a similar process to Chrome.

4. Safari ERR CERT AUTHORITY INVALID Error

Safari users give “Your connection is not secure” error, which indicates a problem with the website certificate and encryption. These errors in Safari are usually caused by websites with expired SSL certificates.

How To Fix the NET::ERR_CERT_AUTHORITY_INVALID Error?

We learned the structure of this error message in the most preferred famous internet browsers. Now it’s time to take the lead for NET::ERR_CERT_AUTHORITY_INVALID error solution. Earlier in our article, we provided information on the most common causes of this error. However, we mentioned that local configuration errors can also trigger this issue in some cases.

Therefore, there are many ways to solve this problem. To make our job easier, from the three most common sources of this error; i.e. we will start with expired, self-signed and untrusted certificates. Then we will touch on more general solution methods.

If we list the solution methods that we will consider for the NET::ERR_CERT_AUTHORITY_INVALID solution:

  1. SSL Query Tool
  2. Obtaining an SSL Certificate from a Valid Source
  3. SSL Certificate Renewal
  4. Reloading the Page (Or Using Incognito Mode)
  5. Clearing Browser Cache (And Clearing Cookies)
  6. Setting the Computer Clock
  7. Using a Different Network
  8. Disabling VPN or Antivirus Software
  9. Clear SSL State

1. SSL Query Tool

If you have an SSL certificate, something may have gone wrong during the installation of the certificate. This usually happens during manual SSL certificate installations on websites.

The easiest way to check if your SSL certificate is properly installed is to use an SSL Query Tool from Qualys SSL Labs. These tools are completely free and can guide you.

The usage patterns of SSL query tools are very similar to each other. All you have to do is find a testing tool and enter your domain in the box. After the inquiry, the tool will provide you with the relevant reports.

After applying this solution, be sure to check whether the NET::ERR_CERT_AUTHORITY_INVALID Google Chrome error has been resolved by entering your website.

2. Obtaining an SSL Certificate from a Valid Source

Using a self-signed certificate is very practical and inexpensive nowadays. Therefore, we strongly recommend Let’s Encrypt to get an SSL certificate from a reliable source at no cost. All SSL certificates obtained from here -as Let’s Encrypt is an authority- will be validated.

After applying this solution, be sure to check whether the NET::ERR_CERT_AUTHORITY_INVALID Google Chrome error has been resolved by entering your website.

3. SSL Certificate Renewal

SSL certificates need to be renewed periodically for security reasons. The renewal process authenticates your domain name, and without this, certificates lose some of their validity. You can repurchase free certificates from Let’s Encrypt every 90 days. However, the paid options are more durable and practical.

Once your certificate expires, your hosting company will take care of it for you. If your hosting company can’t handle it, you can manually renew it yourself.

After applying this solution, be sure to check whether the NET::ERR_CERT_AUTHORITY_INVALID Google Chrome error has been resolved by entering your website.

4. Reloading the Page (Or Using Incognito Mode)

In which browser you are getting NET::ERR_CERT_AUTHORITY_INVALID Google Chrome and other browser error, use the page reload options of that browser. Or, try to access the relevant website in incognito mode by using the incognito mode feature of the browser you are using.

If the website loads fine in incognito mode, it means that the error is most likely caused by your browser trying to load an outdated version of the page. This indicates that you need to clear the cache, which is exactly what the next item is about.

5. Clearing Browser Cache

Cache Clearing menus, which may change depending on which browser you are using, are located in the advanced settings section of almost every browser due to their location. Whichever your browser is, you can access the settings menu and clear the cache and cookies in the advanced settings section.

6. Setting the Computer Clock

One of the most common causes of the NET::ERR_CERT_AUTHORITY_INVALID Google Chrome error is incorrect date and/or time settings on your computer. Errors related to your device’s clock can negatively affect your browser’s process of verifying a website’s certificate.

To set the computer clock, simply follow these steps:

  • Right click on the time and date on the Taskbar.
  • Select “Set date/time” from the drop-down menu.
  • In the Settings window that opens, activate the “Set time automatically” option.
  • Click “Sync now” in the “Sync your watch” section.

After applying this solution, be sure to check whether the NET::ERR_CERT_AUTHORITY_INVALID Google Chrome, Safari and other browser error has been resolved by going to the relevant website.

7. Using a Different Network

In some cases, you may get a NET::ERR_CERT_AUTHORITY_INVALID error when you use a public network such as cafes, malls or those connected to tourist attractions. These networks are often not good at routing data traffic securely. Therefore, error may be inevitable.

If you received the error through the internet connection you access from your computer, we recommend that you try to open the web page where you received the error with a device that offers mobile data option. If you don’t get the error on a website with mobile data turned on, the problem may be related to the internet connection on your computer.

8. Disable VPN or Antivirus Software

If you got the NET::ERR_CERT_AUTHORITY_INVALID error with the VPN, the VPN may also be the cause of this error.

In addition, one of the most known sources of this error is antivirus software. If you do not get any results after trying all other solutions, we also recommend that you temporarily disable your VPN connection and antivirus software.

After completing these steps, try to access the website again. But of course after clearing your browser’s cache and cookies.

9. Clear SSL State

Your computer temporarily caches copies of certificates from previously visited websites. Thus, it prevents a re-verification process every time you access the sites.

Your SSL state is like a cache built for certificates only. You can also use “Clear SSL State” when you get an invalid certificate error, as with clearing the browser cache. This helps you to clear your SSL cache. To clear the SSL cache, follow these steps on your computer:

Control Panel >> Network and Internet >> Internet Options >> “Content” tab >> Clear SSL State

Check if the NET::ERR_CERT_AUTHORITY_INVALID error has been resolved by going to the relevant website.
