How to Fix "SSL Handshake Failed" Error
Setting up a Secure Sockets Layer (SSL) certificate for your website has never been easier. You can generate certificates for free, and many hosting providers will even set them up for you. However, if you don’t set up your certificate correctly, you may encounter errors like “SSL Handshake Failed.”

The “SSL Handshake Failed” error appears when your browser and ghana phone number data are unable to establish a secure SSL connection. This article will explain what an SSL handshake is and what to do to resolve the SSL error.

Let's get started!

What is an SSL handshake?
As you may know, an SSL certificate validates the “identity” of your website. It does this by using an encrypted key that your browser checks to make sure the certificate is valid. Once a connection is established, your browser can decrypt the content the server sends it.

This process is called “handshake”. Here’s how it works in more detail:

You visit a website with an SSL certificate and your browser sends a request for data.
The server sends an encrypted public key to the browser.
Your browser checks that key and sends its encrypted key to the server.
The server decrypts the key and sends the encrypted content to the browser.
Your browser decrypts the contents (thus completing the handshake).
All of this happens in a matter of seconds. SSL certificates and HTTPS allow your website to transmit data securely, without negatively impacting performance. This makes an SSL certificate vital for any website. However, like any element of your site, it can occasionally cause problems.

What causes SSL Handshake Failed error?
The SSL connection error tells you exactly what the problem is. It appears when your browser fails to establish a connection to a website that has an SSL certificate:

SSL handshake failed error
In this example from a website using Cloudflare , you can see that the “SSL handshake failed” error is coded “525”. Therefore, the error can be caused by either server-side or client-side issues.

The most common causes of the SSL connection failed error include:

Your local device has the wrong date or time
Your browser does not support the latest SSL protocol
Your SSL certificate is invalid
There was a problem configuring Server Name Identification (SNI)
There is a problem with your Content Delivery Network (CDN) , such as Cloudflare
This list includes two local issues, two related to your website server, and one specific to a third-party service. In the next sections, we'll explore how to address each of these.

How to Fix SSL Handshake Failed Error (5 Methods)
We will start by showing you how to fix client-side issues that can cause the “SSL Handshake Failed” error. These solutions are pretty simple. If they don’t work, we will move on to more technical solutions.

1. Update the date and time of your local device
When your browser attempts to establish an SSL handshake, it checks the certificate against your computer's date and time. It does this to verify that the SSL certificate is still valid.

If your local device's date and time is off, this can cause errors during the verification process (e.g. no handshake). Fortunately, this is a problem with a simple fix.

On a Windows device, open the Start menu and type Date and time settings . Select the option that appears and a new window will open. Enable the Set time zone automatically setting and make sure your time zone is correct.
