Expiration dates are placed on SSL certificates, to help make sure their validation information remains accurate. Generally, the validity of these certificates lasts for anywhere between six months and two years. If an SSL certificate is revoked or expired, the browser will detect this and be unable to complete the SSL handshake. This tool is both reliable and free to use. All you need to do is input your domain name into the Hostname field, and then click on Submit.
On this page, you can find out if your certificate is still valid and see if it has been revoked for any reason. In either case, updating your SSL certificate should resolve the handshake error and is vital for keeping your site and your WooCommerce store secure. Sometimes the best way to determine the root cause of an issue is by process of elimination.
As we mentioned earlier, the SSL handshake failure can often occur due to a browser misconfiguration. The quickest way to determine whether a particular browser is the problem is to try switching to a different one.
This can at least help narrow down the problem. You may also try disabling any plugins and resetting your browser back to its default settings. Another potential browser-related issue is a protocol mismatch. For example, if the server only supports TLS 1. This will inevitably lead to an SSL handshake failure. This will expand a number of menu options. This will open up a new window.
Next, select the Advanced tab. If not, check that option:. The same applies to TLS 1. AH Parent: Could not create exit event for child process". AH Parent: Received shutdown signal — Shutting down the server. AH Parent: Received restart signal — Restarting the server.

Is there an easy way to check? If any of the options are checked and filled in. Your environment has a proxy and may have a certificate installed to strip SSL. I definitely don't see a proxy. I'm in a corporate environment but I have root access on my own computer and set it up from scratch. Do you get a certificate issue in a browser when you go to: index. Show 7 more comments.
