Pling store8/5/2023 To put it simply, both SSL and TLS are authentication protocols, and your certificate may use either one. The most common issue is that your browser doesn’t support the Transport Layer Security (TLS) protocol that your certificate uses. In some cases, you may run into the “SSL handshake failed” error due to problems with your browser. Ensure That Your Browser Supports the Latest TLS Protocol If fixing the date and time on your local device doesn’t do the trick, you can move on to the next fix. Here’s how to fix your date and time on other Operating Systems (OSs): Verify that your date is now correct, and then try to reload the website. Enable the setting Set time automatically, and ensure that your time zone is correct: Select the option that appears, and a new window will pop up. On a Windows device, open the Start menu and type in Date & Time settings. Fortunately, this is an issue with a simple fix. If your local device’s date and time are off, that can lead to errors during the verification process (i.e., no handshake). It does this to verify that the SSL certificate is still valid. When your browser tries to establish an SSL handshake, it verifies the certificate against your computer’s date and time. In case they don’t work, however, we’ll then move on to more technical solutions you can try. Here, we’re going to start by showing you how to fix the client-side issues that can cause the “SSL handshake failed” error. How to Fix the “SSL Handshake Failed” Error (5 Ways) In the next sections, we’ll explore how to tackle each of them. That list includes two local issues, two that are related to your website’s server, and one that’s specific to a third-party service. There’s an issue with your Content Delivery Network (CDN), such as Cloudflare.There’s a problem with your Server Name Identification (SNI) configuration.The browser doesn’t support the latest SSL protocol.Your local device has the wrong date or time.The most common causes of the “SSL handshake failed” error include: Thus, the error can stem from both server- and client-side problems. In this example from a website using Cloudflare, you can see that the “SSL handshake failed” error corresponds to the “525” code. It shows up when your browser fails to establish a connection with a website that has an SSL certificate: The “SSL handshake failed” error tells you precisely what the problem is. What Causes the “SSL Handshake Failed” Error However, like any element of your site, it can occasionally create unique problems. That makes an SSL certificate vital for any website. SSL certificates and the HTTPS protocol enable your website to transmit data securely, without negatively impacting performance. Your browser decrypts the content (hence completing the handshake).Īll of this happens in seconds.The server decrypts the key and sends encrypted content back to your browser.Your browser checks that key and sends its encrypted key back to the server.The server sends the browser an encrypted public key.You visit a website with an SSL certificate and your browser sends a request for data.Once you establish a connection, your browser can decrypt the content that the server sends it. It does that using a cryptographic key that your browser checks to make sure the certificate is valid. Let’s get to it! What Is an SSL Handshake?Īs you may know, an SSL certificate validates your website’s “identity”. This article will explain what an SSL handshake is and what to do if you fail to establish one. The “SSL handshake failed” error shows up when your browser and the server can’t establish a secure connection. However, if you don’t configure your certificate properly, you may encounter errors such as “SSL handshake failed”. You can generate certificates for free, and many hosting providers will even set them up for you. Setting up a Secure Sockets Layer (SSL) certificate for your website has never been easier.
