How To Fix ‘ERR_CERT_AUTHORITY_INVALID’ Issue in Google Chrome – Guide
Even if you have SSL certificate installed on your website, your users may encounter NET::ERR_CERT_AUTHORITY_INVALID error. Despite its intimidating name, the invalid certificate authority error is nothing to panic. Simply put, your browser does not recognize the validity of your certificate. To keep it “safe”, it will display this error to let you know something is suspicious. However, as a website owner, there is a lot you can do to fix the problem. In many cases, browsers actively block users from accessing the site to protect them. This usually comes in the form of the error “Your connection is not private”. As you can imagine, this is a big problem when it comes to up on your own website. If you encounter the error “NETERROR_CERT_AUTHORITY_INVALID” (or sometimes called “ERR_CERT_AUTHORITY_INVALID” or “NET::ERR_CERT_AUTHORITY_INVALID”) in Google Chrome, you are not alone. Thousands of users across the world face this annoying SSL error and it is irritating to say the least. If you are looking for a solution through this post, you are a website owner whose website is experiencing this error or you are a user who wants to access a specific website who is showing this error message. In the next few paragraphs, we will show you the many faces that this error can take and then we will talk about how to fix it.
Disable firewall SSL checking
Most antivirus programs are also built into the firewall application. The main function is to prevent the user from accessing websites that do not follow the SSL protocol. At the same time, they also give users the flexibility to temporarily disable this setting. As for the above error, it could be that the firewall is not allowing you to access the non-SSL websites. To work around this limitation, you may need to disable it feature in your firewall/antivirus application. It could be done like this:
BitDefender:
Kaspersky:
Avast:
On the other hand, there is no option to disable SSL in Windows Firewall. Instead, you can temporarily disable Firewall while browsing the site.
Delete Chrome Cache
In some cases, the website may have already updated its SSL certificate, but your browser would still show the error ERR_CERT_AUTHORITY_INVALID. The reason can be attributed to the fact that instead of loading this website from scratch, the browser still shows the cached copy of the website. To fix this issue, you would have to delete the browser cache files.
Here are the steps to clear Chrome browser cache data:
Delete System SSL Cached Files (Windows)
Always checking that Secure Socket Layer is implemented on websites can decrease the overall load time of affected websites. The system saves the SSL status of each website you visit. So, instead of repeatedly running the SSL check, the browser simply extracts this information from the system’s cached SSL files. However, if the website in question has just added or updated its SSL, it will not show up in your browser (as you are still choosing up the oldest cached files). So, to fix this issue, you should consider clearing incoming system SSL states.
Here are the steps to delete cached SSL certificates from Windows OS:
