This Error occurs particularly when your browser can’t verify the validity of your website’s SSL certificate. Or even if you haven’t set up a certification or using HTTP for your website. This isn’t recommended for security; you shouldn’t run into this Error. 

The three primary causes for this NET::ERR_CERT_AUTHORITY_INVALID Error are:

  • You’re using a self-signed certificate to save money.
  • The certification comes from a non-trusted source.
  • The validity of your certification has expired. 


If the first two reasons are valid, we recommend changing your approach. Your website’s visitors may run into the NET::ERR_CERT_AUTHORITY_INVALID error. And those browser warnings may scare many users away, which is not a good sign. 

And if the last reason is valid, renewing your certificate is advisable. Or you can also automate this process if it’s possible to do so.

So, now that we know the reasons for this Error. Let’s look into the top 4 ways to fix the NET::ERR_CERT_AUTHORITY_INVALID Error.

Problems with Certificate

Get a Signed Certificate from a Valid Authority if you don’t have one. The provider’s validity should not be compromised when getting a signed certificate for your website. If you think money is an issue, you can get a free certificate from a valid provider like Let’s Encrypt.

Browsers usually tend to recognize the certificates offered by these valid providers. But for some websites, you will need more than just a free certificate to ensure security and reliability.

The main reason is that free certificates need renewal very often, which can be cumbersome.

On the other hand, Premium certificates offer many positive perks other than security, such as insurance in case of data breaches, robust encryption for multiple domains, and so on. And in case you already have a valid SSL certificate, it’s time to renew it. 

Problem with Browser Cache and Cookies:

Another way to fix this issue is by clearing your browser’s cache and cookies, as the Error is more likely to be caused by your web browser attempting to load an outdated cached page version.clear browsing data

If your browser supports that option, you can check it quickly by accessing the same website using an ‘incognito mode.’ You may even try to reload the page to check if this Error disappears. It only takes a second. 

Problem with your network or AV:

If you are trying to access the site on a VPN connection or a public network, you’ll most likely face this Error. In such cases, the best recommendation is to temporarily turn off your VPN or switch to a more secure network.
