Is the NET::ERR_CERT_DATE_INVALID error on your Google Chrome browser blocking you from accessing your favourite website? With over 51% of frequently visited websites using an SSL certificate, you are bound to come across SSL errors from time to time.

While some websites install SSL for SEO purposes, others are compelled to do so. Laws and regulations such as the GDPR in the European Union and the HIPAA in the US require website owners to implement security measures to protect user data.

Once the SSL is installed, most webmasters and administrators fail to keep track of its validity, leading to SSL errors.

Speaking of the ERR_CERT_DATE_INVALID also known as “Your Connection is Not Private” error, it is one such SSL glitch that occurs when there is a problem with the date of the certificate and the system or both.

With that said, let’s find out how website owners and Chrome users can troubleshoot this issue.

Let’s first discuss if it is worth your time and effort!


So as to deliver a superior user experience and better security, the Chrome browser shows many security warnings. So, the golden rule for secure internet browsing is never to ignore nor bypass SSL security warnings, especially when it shows up on your Google Chrome Browser, which is trusted by over 66% of internet users worldwide.

However, there are times when you would want to bypass these security warnings, but can you ignore them? No! you need to know the risk involved.

A website that does not have a valid SSL certificate does not offer client-server encryption. So, your interaction with the website can be intercepted by cybercriminals.

This makes it risky to exchange sensitive data such as login credentials, personal or financial information, etc.

However, if you are researching some topic and wish to read something on a website that shows the NET::ERR_CERT_DATE_INVALID error, the risk is minimal.

What Should Website Owners do about the NET ERR_CERT_DATE_INVALID error?

If you own a website that shows up the ERR_CERT_DATE_INVALID error, check your SSL certificate’s validity.

If you installed a freebie that came bundled with the web hosting plan, you must know that those free certificates usually remain valid for 90 days only, after which you must renew them.

On the other hand, if you or your developer has installed one from a reliable source, you still need to know that SSL certificates remain valid for a maximum of two years only.

How to Fix the NET ERR_CERT_DATE_INVALID error on the Chrome Browser?

3. Remove Extensions and other Applications

If you use Google Chrome, you may have experimented with browser extensions, and one of those could be obstructing the SSL connectivity. You can experiment with that by opening the same website in an incognito window. If the website opens there, it only means that your regular Chrome Window has a faulty Chrome extension that needs to be uninstalled.

To remove Chrome Extension:

Step #1: Click on the three vertical dots on the top-right corner.

Step #2: Click on the ‘Settings’ option.
