Google Chrome is the most used browser we have today. This is a testament to how robust and user-friendly it is. That said, you may need to ignore certificate errors on Chrome especially since this is an issue you may experience from time to time.

SSL certificates are standard security solutions used to encrypt data between a visitor’s web browser and a website. Visitors will feel much safer on SSL-encrypted sites because they keep sensitive data like payment information and data safe.

The HTTPS in the URL and the padlock icon shown within an address bar are indicators that the site is encrypted.

Unencrypted sites may experience conversion and traffic rate drops. These sites are not only marked as insecure in Google Chrome, but they are also shunned by 85 percent of internet users.

You can also use any of these three methods to secure your certificate when Chrome says it’s not valid

In this article, we will cover the basics of security errors and show you the best ways you can fix them.

Why am I getting certificate errors on all websites Chrome?

Certificate errors are among the common Chrome errors encountered, but because there are a host of them, the reason behind a problem is going to be specific to the certificate error message you get.

Broadly speaking, these errors will be triggered anytime there is one form of error or the other with accessing SSL/TLS certificates.

Below are a few common certificate errors and why you may be seeing them.

  • NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED – When you access an HTTPS site with SSL/TLS Certificate problems, you could trigger this Chrome browser error message.
  • ERR_SSL_VERSION_OR_CIPHER_MISMATCH – When website browsers and website servers don’t support the same SSL protocol edition, you will get this error message.
  • NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM – This error occurs when the server and your computer do not have a secure SSL connection or when the SSL certificate is expired, not correctly configured, or doesn’t correspond to the domain you are attempting to access.
  • ERR_SSL_PROTOCOL_ERROR – You are getting this message because you have an incorrect date configuration on your computer.
  • NET::ERR_CERT_AUTHORITY_INVALID – Issues with the network, your device, or a browser may be causing the error by preventing the SSL certificate from being correctly read.
  • ERR_CERT_SYMANTEC_LEGACY – This error commonly arises because a Symantec SSL / TLS certificate issued before June 1, 2016 is no longer recognized by Google Chrome.
  • NET::ERR_CERT_COMMON_NAME_INVALID (this occurs when the certificate does not match the domain)
  • ERR_CONNECTION_REFUSED – This is usually due to a server-side issue and not the individual connection attempt.

With this said, let us consider the best ways to ignore or avoid certificate errors.

How do I turn off certificate checks?

1. Chrome ignore certificate errors localhost

  1. Launch the Chrome browser.
  2. On the address locator input the link below.
    chrome://flags/
    chrome ignore certificate errors
  3. Type secure in the search box and click enter.
    chrome ignore certificate errors
  4. Scroll down to the Allow invalid certificates for resources loaded from localhost flag.
  5. Click on the dropdown list and select Enabled.
    chrome ignore certificate errors
  6. Restart the browser and try to reaccess the link.

Following these steps will allow all invalid certificates for resources loaded from localhost.

Note that flags are experimental settings open to the public by Chrome. This implies that after a while some flags that currently exist may be removed, while others may become permanent features in the browser.

Lastly, we highly recommend that you should only enable the Allow invalid certificates for resources loaded from localhost flag, if you are confident and trust the websites you are visiting. If these are not trusted websites, they may introduce malware and serve as a security breach.

How do I stop SSL certificate warning messages?

The above solutions will be valuable ways of avoiding SSL certificate warning messages. As we mentioned earlier the errors you get can be caused by a range of factors.

We highly recommend regular housekeeping on your computer. A few preventive steps to stop certificate warning messages include:

  • Set your time and date – In most cases, your time and date by default should be correct, but there are times when you need to reset or save the settings. As a top recommendation, you should allow your computer to automatically select time and date.
  • Use a fresh copy of the browser – If you constantly receive certificate errors on Chrome, you should consider uninstalling and reinstalling a new version. This way, settings associated with the old version are cleared.
  • Use an updated version of Chrome – Outdated apps are prone to bugs and may have stored old settings. If these settings are not removed, you may get certificate errors. We advise constant updates of the Chrome browser.
  • Get rid of cache and old cookies – Old cookies and cache contain information from sites that have been visited. If this info changes and the cache and cookies are not clear, the certificate error may be triggered.

There you have it. If you have encountered any certificate errors on Chrome, with these fixes you should be able to resolve them. Please note that some error messages are for your protection, and in these cases, you should avoid visiting affected websites.
