As an example, we’ll look at how the process works in Chrome. How you can check to see if this problem is occurring varies based on the browser you’re using. This will inevitably lead to an SSL handshake failure. For example, if the server only supports TLS 1.2, but the browser is only configured for TLS 1.0 or TLS 1.1, there’s no mutually-supported protocol available. You may also try disabling any plugins and resetting your browser back to its default settings.Īnother potential browser-related issue is a protocol mismatch. This can at least help narrow down the problem. The quickest way to determine whether a particular browser is the problem is to try switching to a different one. As we mentioned earlier, the SSL handshake failure can often occur due to a browser misconfiguration. Sometimes the best way to determine the root cause of an issue is by process of elimination. Configure Your Browser for the Latest SSL/TLS Protocol Support In either case, updating your SSL certificate should resolve the handshake error (and is vital for keeping your site and your WooCommerce store secure).ģ. On this page, you can find out if your certificate is still valid and see if it has been revoked for any reason.

If an SSL certificate is revoked or expired, the browser will detect this and be unable to complete the SSL handshake. Generally, the validity of these certificates lasts for anywhere between six months and two years. Check to See If Your SSL Certificate Is ValidĮxpiration dates are placed on SSL certificates, to help make sure their validation information remains accurate. Of course, if your clock is showing the correct information, it’s safe to assume that this isn’t the source of the “SSL Handshake Failed” issue. Whatever the reason, it’s a good idea to check and make sure your system time is correct, and update it if it’s not. Your computer’s clock might have been set incorrectly due to human error or simply due to a glitch in your settings. When the system clock is different than the actual time, for example, if it’s set too far into the future, it can interfere with the SSL certificate verification. If your system is using the wrong date and time, that may interrupt the SSL handshake. Let’s start with one of the more unlikely causes, but one that is incredibly easy to correct if it is the problem: your computer’s clock. Let’s take a look at five strategies you can use to try and fix the SSL Handshake Failed error. So there’s no simple answer when it comes to how you should fix it.įortunately, there are a handful of methods you can use to begin exploring potential issues and resolving them one by one. There are several potential causes behind the “SSL Handshake Failed” error. How to Fix the SSL Handshake Failed Error (5 Methods) Typically, if the SSL handshake fails, the issue can be attributed to something wrong with the website or server and their SSL configurations. A certificate that is incomplete, invalid, or expired. A protocol used by the client that isn’t supported by the server.A connection that is being intercepted by a third party.An error with the browser configuration.The wrong date or time on the client device.Common causes of SSL errors on the client-side include: However, it’s also important to understand that SSL errors can happen on the client-side or the server-side. Generally, an Error 525 means that the SSL handshake between a domain using Cloudflare and the origin web server failed: This can happen for a variety of reasons. Understanding What Causes SSL Handshake FailuresĪn SSL Handshake Failure or Error 525 means that the server and browser were unable to establish a secure connection.
