Essentially the error means your internet connection or the device prevents google chrome from loading. However, chrome thinks that the web page is insecure and maybe a potential threat. 

See if the issue your computer or website:

On the web page, you’ll want to find the two dates listed under the issuer. It should say the “Expires On” date and “Current Date.” 

Make sure the expires date is a time in the future. If the expiration date is today or in the past, this means that the website has an invalid SSL certificate. However, if the current date is not the exact current date, this will be your computer’s issue.

If The Ssl Certificate Is Expired: 

First off if the website isn’t yours, there isn’t much you can do about the website not loading. You’ll simply have to try to contact the website owner to let them know about the net::err_cert_date_invalid error you’re seeing and which website it appears in. 

Now if you do manage the website, you’ll need to purchase a new SSL in order to validate your website and get it up and running. 

Step 1) Simply purchase a new SSL certificate. Which one you buy depends on what you kind of website you’re trying to operate:

  • If you just need a basic HTTPS SSL security, a basic DV certification will suffice. 
  • If your website has numerous subdomains such as:,, etc, you’ll need a wildcard SSL certificate. 
  • If you have an e-commerce or financial site, you’ll need an EV certificate which allows you to have a green address bar.

Step 2) Go through the purchase and finish the validation process. You’ll need to verify via email or upload a verification file to your website. 

Step 3) Install the new SSL certificate to your website. Each SSL certificate may be different so follow the instructions of the issuer. You can go to their customer support if you need further help.
