What Is SSL Handshake Failed Error? How to Detect and Fix It Effectively

SSL Handshake Failed Error is easier to understand when the core ideas are explained in practical terms. This guide covers what it means, how it works, why it matters, and the main details you should know.

What Is SSL Handshake Failed Error?

The SSL Handshake Failed error occurs during the authentication and establishment of a secure connection between a browser and a web server. This process, called the SSL handshake, involves the client and server exchanging information to establish a secure communication channel via the SSL/TLS protocol.

What Causes SSL Handshake Failed Error?

The 'SSL Handshake Failed' error can be caused by a variety of reasons. Below are some of the common causes of the SSL Handshake Failed error.

Client Is Setting Wrong Date and Time

The date and time of the Client computer plays an important role in the SSL certificate validation process. The SSL certificate may be considered invalid, causing the browser to refuse to connect to the web server, causing the SSL Handshake Failed error if the date and time on the computer is incorrect.

Client Browser Settings Are Incorrect or Outdated

The web browser can also be the cause of the SSL Handshake Failed error. Unless the browser is misconfigured or outdated, it will not support the protocols and encryption algorithms required for the SSL Handshake process.

The Client Side Is Using Third Party Software That Is Blocking the Connection

Some security software or ad blockers can interfere with the SSL Handshake process. These software can intercept or change the information sent between the browser and the web server, resulting in the SSL Handshake Failed error.

The Server and Client Sides Are Not Using the Same Encryption Algorithm

Another cause of the SSL Handshake Failed error is that the browser and the web server are not using the same set of encryption algorithms. This can happen if either side is not updated to the latest version or if the web server's security configuration is faulty.

The Server Doesn't Support Some Protocols That the Client Is Using

Some web servers may not support all of the security protocols that web browsers use. The SSL Handshake Failed error will occur if your browser uses a protocol that the server doesn't support.

Invalid Server or Client SSL Certificate

Finally, the SSL certificate may be faulty or expired. The browser will refuse to connect and display the SSL Handshake Failed error if the certificate is not issued by a trusted certificate authority.

How to Fix SSL Handshake Failed Error Effectively

Below are some effective ways to fix SSL Handshake Failed error that you can apply.

Check Your System Date and Time

First, users need to confirm that the date and time on their computer are set correctly. This can be easily done in the control panel of Windows or other operating systems.

How to fix SSL Handshake Failed error.

You can set it to automatically synchronize its time with a time server, avoiding problems related to incorrect date and time if your computer is connected to the internet.

How to do:

• On Windows: Right-click the clock in the lower right corner, select "Adjust date/time" and check the settings.
• On macOS: Open "System Preferences" > "Date & Time" and make sure the time is set correctly.

Check SSL Certificate Validity

Use online tools like SSL Checker to check the validity of your web server's SSL certificate. This tool will provide detailed information about the certificate, including the expiration date and the certificate authority. The user should contact the server administrator to request an update or replacement if the SSL certificate is invalid.

Always Update Your Browser to the Latest Version

Be sure to keep your browser up to date to ensure it fully supports the necessary protocols and encryption algorithms. Developers regularly release updates to improve security features and fix bugs.

Users should regularly check for updates for their browser and update as soon as possible.

Check TLS/SSL Protocol Support

Users should also check whether the web server supports the necessary TLS/SSL protocols. You will find many online tools that can help test a server's protocol support, which can help determine if there are any issues.

The user can contact the server administrator for assistance if the server doesn't support the required protocol.

Make Sure the Server Is Properly Configured for SNI

SNI (Server Name Indication) is a security feature that allows a web server to use multiple SSL certificates for multiple domains on the same IP address. Ensuring that the server is properly configured for SNI will help avoid the SSL Handshake Failed error.

Users can ask the server administrator to check and reconfigure SNI if necessary.

Configure Supported Protocols and Cipher Suites

Finally, the web server needs to be configured to support the most popular protocols and Cipher Suites. Users can refer to the official documentation to ensure that the web server is configured correctly.

You can contact their web service provider or system administrator for further assistance if the above methods don't resolve the issue.

Conclude

The SSL Handshake Failed error can be caused by a variety of factors, from system settings to server configuration. However, by understanding the causes and applying effective fixes, you can quickly resolve this error and continue browsing the web safely.

Final Thoughts

The most reliable way to handle SSL handshake failed error is to follow the process in order, verify each important setting, and test the result before moving on. Use the guidance above as a practical reference, then adjust the details for your device, software version, or specific goal.
