🛡️ What is NET::ERR_CERT_AUTHORITY_INVALID error?

The "NET::ERR_CERT_AUTHORITY_INVALID" error is a common issue encountered while browsing the web, typically in Google Chrome or other web browsers. It occurs when the browser detects a problem with the SSL certificate of a website, indicating that the certificate authority (CA) issuing the certificate is not recognized or trusted. Essentially, the "Chain of Trust" that links the website to a verified root provider has been broken.

SSL (Secure Sockets Layer) certificates are digital certificates that encrypt data transmitted between a user's browser and a website's server, ensuring a secure connection. These certificates are issued by trusted certificate authorities, which verify the authenticity of the website. Without a valid certificate, your data is vulnerable to "man-in-the-middle" attacks where hackers can intercept sensitive information.

When a browser encounters an invalid SSL certificate, it displays the "net::err_cert_authority_invalid godaddy " error message to warn the user that the website's connection may not be secure. This can happen for various reasons, such as an expired certificate, a misconfigured certificate, or a self-signed certificate. For those running high-performance websites on an SSD VPS, keeping these certificates updated is a top maintenance priority.

🔍 What are the NET::ERR_CERT_AUTHORITY_INVALID error variations?

The " net err_cert_authority_invalid chrome problem " error is a common hurdle encountered by users navigating the internet.

🛠️ How to fix net::err_cert_authority_invalid

Earlier, we discussed the most common causes of the NET::ERR_CERT_AUTHORITY_INVALID error, but we also mentioned that your local configuration can cause net::err_cert_authority_invalid in some instances. To keep things simple, we start by tackling the three most common culprits, which are expired, self-signed, and 'untrustworthy' certificates. We then move on to more general solutions to net::err_cert_authority_invalid. If you are managing your own infrastructure, using a managed VPS can often prevent these issues as the provider handles certificate renewals for you.

1. 🧪 Run an SSL server test

The setup process may have gone wrong if you installed your SSL certificate manually, instead of through your web host, shortly before you started seeing the error. Checking your certificate's installation is easy by using an SSL check tool, such as Qualys SSL Labs'. This particular tool is free to use. To fix the error, you simply have to enter the domain in which it is appearing, and click the Submit button:

Wait a couple of minutes while the results appear. If all of your certificates are perfect, you should get an A+:

The tool should have a section that tells you whether your certificate is trustworthy or not if you don't get a perfect score. If the tool does not give you a perfect score, you need to install a certificate from a trusted source. For those using Nginx, you can learn how to configure SSL with Nginx to avoid these common pitfalls.

2. 📜 Get a certificate from a valid authority

Today, there's no reason to use a self-signed certificate for public-facing websites. You can get free certificates from providers like Let's Encrypt that are recognized by all popular browsers. We offer free SSL certificates for customers through automated integrations! SSL starts working automatically without any additional configuration thanks to modern cloud platforms.

It is possible that some website owners will require features not available from free certificate providers, such as Organization Validation (OV) or Extended Validation (EV). If you are looking to buy dedicated server hosting, ensure your provider supports easy SSL installation via the control panel.

3. 🔄 Renew your SSL certificate

SSL certificates must be renewed for security reasons periodically—usually every 90 days for free certificates or 1 year for paid ones. The renewal process verifies your domain's identity, and certificates lose some of their validity without it. Custom SSL certificates will always require manual or automated renewal. If you need a replacement, follow our guide on how to reissue a RapidSSL Certificate.

This error occurs when your computer's clock is set incorrectly. To clarify, this error occurs when your browser cannot verify a website's certificate because your device's clock is outside the certificate's "valid from" or "valid to" dates. When this happens, you can adjust your computer's clock in seconds.

Windows

Right-click the time on your computer's system tray, then select the option that says Adjust date/time to net::err_cert_authority_invalid:

Find the Sync now option under Synchronize your clock under the Settings window, and click on it. This ensures your local time matches the global atomic clock.

Your goal here is to determine if the original network (and its DNS or firewall settings) caused the issue. If the error goes away, you might need to how to change DNS server settings to a more reliable provider like Google or Cloudflare.

8. 🛡️ Disable your VPN or antivirus software

NET::ERR_CERT_AUTHORITY_INVALID may be triggered by the service itself if you're already using a VPN. The most common culprit is antivirus software with "HTTPS Scanning" or "Web Protection" features. These tools act as a proxy and use their own certificates, which browsers may reject.

Once you've tried everything else, you should temporarily disable your VPN and antivirus software. Then try accessing your site again and force refresh your browser to ensure it isn't loading from your browser's cache. If you find your VPN is the cause, consider using a v2ray server for a more secure and customized proxy experience.

9. 🧼 Wipe your computer's SSL state

Whenever you access a certificate from a website, your computer caches it so you don't have to run through the entire verification process each time. However, if the cached certificate is corrupt or outdated, the error will persist.

Your SSL state is like a cache only for certificates. Just like with your cache, your computer's SSL state can be wiped if there is an error with the certificate authority. In Windows, go to Control Panel > Internet Options > Content and click Clear SSL State.

Simply click on the Finder icon, followed by Go > Utilities > Keychain Access to net::err_cert_authority_invalid:

You can delete untrusted certificates by clicking on Edit at the top of the screen, followed by Delete under the Category section.
