What Does Cannot Communicate Using SSL Mean

Learn about the implications of ‘Cannot communicate using SSL’ errors and how to address them effectively to ensure online security and user trust.

Understanding SSL

SSL (Secure Sockets Layer) is a standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the server and the browser remains private and secure. However, sometimes users encounter errors where they cannot communicate using SSL.

Common Causes

One common reason for this error is an expired SSL certificate. When a certificate expires, the secure connection cannot be established, resulting in the error message. Another reason could be an incorrect SSL configuration on the server or browser, leading to communication issues.

Examples of SSL Errors

Imagine trying to access your online banking account and receiving a ‘Cannot communicate using SSL’ error. This could prevent you from securely logging in and conducting transactions, putting your sensitive information at risk. Similarly, e-commerce websites that rely on SSL to protect customer payment details could face a loss of trust if SSL errors occur during the checkout process.

Case Studies

In 2017, Google Chrome started flagging websites without SSL certificates as ‘not secure,’ leading to a spike in SSL adoption rates. However, many websites faced challenges in implementing SSL properly, resulting in communication errors. One such case was a popular e-commerce site that saw a significant drop in sales due to SSL errors during checkout.

Statistics and Impact

According to a survey by HubSpot, 85% of people will not continue browsing or shopping on a website if it is not secure. This highlights the critical role SSL plays in online security and user trust. Additionally, businesses that fail to address SSL errors risk losing customers and damaging their reputation.


In conclusion, ‘Cannot communicate using SSL’ errors can have serious consequences for both users and businesses. It is essential to address these issues promptly by ensuring SSL certificates are up-to-date and correctly configured. By prioritizing online security, businesses can protect customer data, build trust, and avoid potential revenue losses.
