What is the error "This site can't provide a secure connection"?

The "This site can't provide a secure connection" error appears when a website does not comply with the HTTPS protocol . This error is often caused by not having an SSL certificate on the website, not automatically using HTTPS, having an expired or invalid SSL certificate, or an outdated SSL cache in the browser.

Causes of the error "This site can't provide a secure connection"

There are 6 common reasons why browsers display this error.

No SSL certificate installed

The error message may appear because the website does not have an SSL certificate installed. This means that you are accessing the website via an HTTP connection and the destination server sends all requests and responses in plain text.

The data is not encrypted and can be intercepted by third parties to collect information transmitted between the web server and the browser. This can expose the website to cyber attacks such as malware and man-in-the-middle attacks .

HTTPS is not mandatory on websites

The issue can occur when you have installed an SSL certificate but do not enable the option to force HTTPS. This way, visitors will access the HTTP version of the site instead of the secure URL.

Invalid or expired SSL certificate

You may see this error when the website is using an invalid or expired SSL certificate. This means that the website is currently running over an HTTP connection.

Outdated SSL Cache in Browsers

An outdated or corrupted SSL cache in your browser can contribute to website errors. This can typically happen while you are developing websites or after installing a new SSL certificate.

QUIC protocol enabled

The Quick UDP Internet Connections (QUIC) protocol is enabled by default on the Google Chrome browser . This protocol is used to reduce connection times, improve congestion control, scalability, and multiplexing without Head-of-line blocking.

However, in some cases it can cause SSL issues, such as the “This site can't provide a secure connection” issue.

Incorrect date and time settings

Incorrect date and time settings on your computer can cause Google Chrome to block the website. Incorrect information can cause problems in validating the website certificate. This is why the error occurs.

6 ways to fix the error “This site can't provide a secure connection”

Before you begin, you should check your Internet connection, disable Chrome extensions, and disable SSL scanning on your antivirus and firewall. If the problem persists, here are six troubleshooting methods you can try.

1. Install SSL certificate

Installing an SSL certificate is one of the most effective ways to fix the Can't Provide a Secure Connection error message if you are a website owner. Depending on your web hosting provider, the way to configure the additional layer of security may vary.

If you are a Hostinger user, follow these instructions to force HTTPS connection on your website:

• Click the three dots button next to the problematic domain and select Force HTTPS .

This should allow you to open the website. If the problem persists, try the next method.
