Hostinger Academy What Causes “This Site Can’t Provide a Secure Connection” ErrorThere are six common reasons a browser displays the Site Can’t Provide a Secure Connection message. No SSL Certificate Installed The error message may appear because the website doesn’t have an SSL certificate installed. This means you’re accessing it via an HTTP connection, and the target host sends all requests and responses in plain text. The data is not encrypted and may be intercepted by third parties to gather information passed between the website server and a browser. This may expose the site to potential cyber attacks such as malware and man-in-the-middle attacks. HTTPS Is Not Forced on the Website The issue may occur when you’ve installed the SSL certificate but didn’t enable the force HTTPS option. This way, visitors will access the website’s HTTP version instead of the secure URL. Invalid or Expired SSL Certificate You may encounter this error when the website uses an invalid or expired SSL certificate. This means the site currently runs on an HTTP connection. Outdated SSL Cache in the Browser Outdated or corrupt SSL cache in the browser may contribute to the website error. Usually, this can occur when you’re developing web pages or after installing a new SSL certificate. QUIC Protocol Is Enabled The Quick UDP Internet Connections (QUIC) protocol is enabled by default on the Google Chrome browser. It is used for reducing connection time, improving congestion control, transporting extensibility, and multiplexing without head-of-line blocking. However, in some cases, it can cause SSL problems, such as the Site Can’t Provide a Secure Connection issue. Incorrect Time and Date Settings Time and date misconfiguration on your computer may lead the Google Chrome browser to block the website.
