When using the internet, safety comes first. The GDPR is not the only law protecting internet users from misuse and data theft; ongoing advancements in the internet’s technical structure ensure that you can surf safely. Current internet browsers are continually developing their security capabilities to safeguard their users in order to do this. HTTPS connections have become a near-universal standard for secure data delivery.
Google Chrome is concerned about security. When your browser tries to load a website, you may obtain a “ERR CERT COMMON NAME INVALID” error message. Learn what to do if this occurs.
If Chrome displays the error message “ERR CERT COMMON NAME INVALID,” your alarm bells should start ringing. The red triangle with the exclamation point and the words “Your connection to this site is not secure” isn’t just for show.

Surprisingly, this warning can appear on websites that you are familiar with and frequent. There could be various reasons for this:
There are numerous methods for determining the details of the issue and addressing it in a targeted manner. The most crucial ones will be discussed here.
Check that your browser is up to date and refresh the website.
When you get a “ERR CERT COMMON NAME INVALID” issue, the first thing you should do is refresh the website. You may do this by pressing Ctrl + R (Mac: Cmd + R) on your keyboard or by selecting the circle arrow next to your browser’s address bar. It may also be beneficial to completely close and reopen your browser. Check to see if your browser has been updated to the most recent version.
As a website visitor, you have no control over poorly constructed web server redirections that result in a “ERR CERT COMMON NAME INVALID” issue. You can, however, alter how the site is accessed: Try inputting the desired website’s domain name both with and without the “www.”
Tip
By using the list of accessible browser commands, you can avoid having to hunt through menus and options in your browser. In the address bar, type “about:about” to receive a list of clickable browser commands. Chrome, Firefox, and Edge all support this.
Start by updating all active extensions to see if any browser extensions are causing issues with the website’s security certificate. This menu can be found by going to “about:extensions” or by going to “Settings” (1) > “More tools” > “Extensions” (2).
To see if any browser extensions you’re using are interfering with the security certificate of the website you’re visiting and creating the “ERR CERT COMMON NAME INVALID” issue, deactivate them one by one until you can open the site without getting the error.
Security certificate data is cached by browsers and systems. These could contain expired certificates that conflict with a current, valid certificate.
Clear the cache in your browser.
You can start clearing the data from various time periods.
On your PC, intermediate versions of certificate data are preserved. Error warnings can also be caused by expired data in the SSL cache. To clear this, go to the “Control panel” on your computer and select “Network and internet.”
Your system should automatically set up your internet connection. Access to specific websites may be restricted due to some odd settings. Click “Network and internet” on your computer’s “Control panel.” Select the “Connections” tab in the dialog box.
Antivirus software and firewalls are essential tools for protecting your computer’s data from outside threats. Both of them, however, can restrict SSL certificates or override network settings, resulting in a “ERR CERT COMMON NAME INVALID” message in your browser. It could be worthwhile to temporarily disable these security features to see whether the problem message disappears. Search for “firewall” in Windows to go to your firewall. Settings for your antivirus software can be found in the help menu – this varies by application.
Security certificates for websites are valid for a set amount of time, and they compare the certificate’s validity period to the date and time of the computer accessing the site. When a (new) computer is connected to the LAN/Wi-Fi for the first time, an erroneously set time on the machine can occur. Right-click on the clock in the windows task bar and select “Adjust date/time” to change the date and time on your computer. This should open the Windows settings window, where you should select “Set automatically” for the time and time zone.
Date and time are set in Windows.
Select “Set automatically” for the date and time. The comparison between the certificate’s validity term and the time on your computer should thereafter be successful.
Your computer’s time will now be compared to your network provider’s “internal time,” which means it will be extremely accurate.
Public hotspots can be found all around the world. Before you can use most of them, you must first sign in, and this sign-in frequently uses an insecure connection. As a result, you will not be able to access the hotspot’s sign-in page and will be unable to utilize the network. Instead, you’ll get an error notice that says “ERR CERT COMMON NAME INVALID.” If this happens, load an unsafe site address, such as http://hotspot.tld (without the “s”), into your browser’s address bar. You should now be able to visit the hotspot’s sign-in page.
You can disregard the “ERR CERT COMMON NAME INVALID” error message in Chrome and go to the risky website nonetheless. All unprotected data is sent using this manual method.
Error code ERR CERT COMMON NAME INVALID: Option to go to a dangerous website
Continuing to use a harmful website is dangerous.
On these websites, you should never give out your login information, payment information, or other personal information. The error message “ERR CERT COMMON NAME INVALID” can also indicate that you’ve stumbled across an intentional scam involving a hacked or redirected website. Only browse dangerous websites if you are confident in the owner’s honesty.
When you restart your computer, a lot of temporary data is deleted, including multiple temporary caches. This will fix errors like “ERR CERT COMMON NAME INVALID” and others. When you restart your internet router, the same thing happens.
Tip
Other solutions to the “ERR CERT COMMON NAME INVALID” error should be left to web developers because they may require access to your computer system. You should contact your system administrator at work instead.
