Do you frequently get a “Your Connection Is Not Private” message in Chrome? Also, does it tag along with the “Not Secure” warning in the Google Chrome address bar? You should trust the message and assume that it’s there to protect you from sketchy websites.

SSL stands for Secure Socket Layer, a universally recognized security protocol responsible for ensuring that the websites you visit on the internet are secure and the data exchanged between the web server and your internet browser is encrypted.

SSL certificate errors also have unique error codes with different meanings. In this troubleshooting guide, we’ll show you what some of these error codes mean, the factors causing the errors, and how to get them fixed.

1. Change Computer’s Date and Time

If your computer’s time and date settings are incorrect, the following SSL error codes could show-up in Chrome as you browse web pages.

Net::ERR_CERT_DATE_INVALID

NET::ERR_CERT_AUTHORITY_INVALID

One way to fix this error and prevent future occurrences is to configure your computer to update its date and time settings automatically.

For Windows, open the Settings app and navigate to Time & Language > Date & time and toggle on Set time automatically and Set time zone automatically options.

4. Disable Google Chrome Extensions

Extensions play a vital role in the Chrome ecosystem. Using extensions, one can add more features to the basic Chrome interface and functionality. However, some might not be actively maintained, could be out of date, or develop incompatibilities with new Chrome builds.

If you have dozens of Chrome extensions installed, it can be difficult to figure out which one of them is causing the issue.

Because of that, the easiest solution is to disable all extensions and then enable only the ones you need one at a time.

Step 1: Open Google Chrome, tap on the three-dot menu at the top.

Step 2: Navigate to More tools > Extensions.

Step 3: It will open the Extension menu. Tap on the Remove button and remove Chrome extensions.

5. Use Chrome in Incognito Mode

Disabling all Chrome extensions isn’t a logical solution for most out there, as you may need them in your daily use. Instead, you can opt for Chrome’s Incognito mode to browse the web as it disables all Chrome extensions temporarily.

That can help determine whether malicious extensions are responsible for Google Chrome’s security errors. Tap the three-dotted menu icon at the top-right corner and select New Incognito Window.

If you don’t get the SSL security certificate errors in Chrome while browsing the affected website(s) in an incognito window, you’ve probably installed a bad extension. In such cases, you can apply the trick above and fix the issue.

6. Reset All Chrome Settings

It can help because there are times when tweaking the wrong settings can eventually cause issues with Chrome, especially if you’re enabling beta features.

You can fix all of that by resetting Chrome.

Step 1: Launch Chrome and open Settings.

Step 2: Scroll down and click Advanced to open all settings.

7. Use Chrome Malware Scanner

If none of the above tricks worked, your system might have malware that’s interfering with Chrome. The good news is, Google has integrated an anti-malware scanner that will scan your computer and find any problems.

Step 1: Open Chrome and go to Settings.

Step 2: Scroll down and click Advanced to open all settings.

  • NET::ERR_CERT_AUTHORITY_INVALID
  • NET::ERR_CERT_COMMON_NAME_INVALID
  • NET::ERR_CERT_REVOKED
  • NET::ERR_CERT_AUTHORITY_INVALID
  • ERR_SSL_WEAK_EPHEMERAL_DH_KEY
