When users attempt to connect to a site on Google Chrome, they tend to receive an error message that states, “This site can’t provide a secure connection”. This error occurs on Chrome due to a server problem, or due to the unavailability of a certificate that is used to authenticate clients. Besides the missing authentication certificate, and notwithstanding a server problem, there are other causes too for the SSL connection error. Nonetheless, resolving it on Chrome browser can be done easily following the troubleshooting steps given below.
To disable this experimental protocol, key in chrome://flags/#enable-quic on the address bar of the browser and press the Enter key. In the subsequent menu that pops up, click on Default under the respective protocol’s heading and choose Disabled in the drop-down list. Then, restart Chrome. You should be able to surf the web on the browser without having to encounter the SSL error going forward. If not, go to the next troubleshooting step.
Wrong date and time set on Windows PC may also cause the connection error on Chrome. Hence, you should double check to ensure that both are correct. If you are using Windows 10 PC, search for Date & Time in the search box when on the desktop screen and click on the respective setting to change both.

Then, click on Internet Options to the bottom left side of the screen, choose Content tab in the Internet Properties dialog box, select Clear SSL State, and click OK to confirm the same.
Sometimes, an antivirus in Windows PC may cause conflicts between the software and the browser encrypted data. Hence, you should make an exemption to the scan SSL protocol in the settings of the antivirus. If this helps to troubleshoot the error on Chrome, update the browser, the virus removal software, and the OS. After that, clear the browser data and enable the SSL protocol scanning feature again to see if it works.
