“Expired DigiCert Certificate” error on Chrome
on Windows

Hello, when I try to open particular websites, I receive "Delete Expired DigiCert Certificate” error. I am not sure what does it mean? Is it a serious problem or can I fix it?

"Expired DigiCert Certificate” is one of Google Chrome connection errors that might show up anytime when browsing the web. However, only Mac OS X users might encounter this error. Thus, Windows operating system users cannot be disturbed by this connection error while surfing the Internet using Chrome. However, Windows users encounter other issues due to the recent updates.[ref en-1]

The reason behind this particular error is related to expired DigiCert certificate which is used in some websites that are dealing with private data, such as banking details, credit card information, etc. DigiCert is a company that verifies the authenticity of secure internet sites.[ref en-2]

For instance, banks, online shops and other sites that are working with private information need to ensure that user’s or customer’s data is safe and invisible for third-parties. Thus, this "Expired DigiCert Certificate” error message informs that the owner of the website has not renewed the validation of the certificate.

When browsing the web, you might find that different site addresses might start either with HTTP or HTTPS. The letter S stands for security; thus, the website has a DigiCert certificate. However, you should not think that sites with HTTP are not safe to browse.[ref en-3] It’s not true. 

Actually, the majority of websites use it because they simply do not have to deal with private information and they don’t need to spend money on this certificate. However, if you browse through online shops and think about buying something, you should pay attention to the website address. If it does not have HTTPS, you should look for another retailer in order to protect your personal information. HTTPS uses data encryption to protect your data from third-parties or cybercriminals.
