SSL Handshake Failed Error — Ultimate Guide by Experts

How to fix one of the most common SSL/TLS errors – SSL Handshake Failed Error

An SSL handshake is a process that begins when your browser sends a secure connection request to a web server such as Apache. However, in some cases, you might get the message “SSL Handshake Error” or “SSL Handshake Failed.”

If you’re confused about what that message means, we have the answers. Read on to find out what’s the SSL Handshake Failed Error, why it occurs, and how to fix SSL handshake error.

Cause of SSL Handshake Error

“SSL Handshake Error” is a message you receive when the SSL handshake process fails.

After you send the secure connection request to the web browser, the browser is supposed to send a public key to your computer that’s automatically checked against a list of certificate authorities. Once the certificate has been received, the computer generates a key and encrypts it using the public key.

The SSL Handshake Error occurs if the read access has not been granted to the OS, thus preventing the web server from completing authentication. It indicates that the browser’s connection to the web server isn’t secure.

This can be caused for a number of different reasons:

  • The SSL/TLS protocol being requested is not supported by the server
  • The cipher suite being requested is not supported by the server
  • The hostname in the URL doesn’t match what’s on the certificate
  • The certificate chain is invalid or incomplete
  • The certificate has expired and or is no longer valid
  • The client or server cannot communicate with the SNI servers

Unfortunately for users, many of these issues are server-side and cannot be fixed by you. But there are a few things you can try.

How to Fix SSL Handshake Error

You may be able to fix SSL Handshake Error by following these steps:

  • The .KYR file and the .STH file should have the same prefix. For example, both the files should be called FILE1.KYR and FILE1.STH.
  • Your operating system must have read access to the .STH file. Without read access, the web server cannot complete the authentication process.

Troubleshooting SSL Handshake Failed Apache

“SSL Handshake Failed” errors occur on Apache if there’s a directive in the configuration file that necessitates mutual authentication.

In order to fix the SSL Handshake Failed Apache Error, you have to follow these steps:

Open the conf file.

  • Replace “SSLVerifyClient” or “SSLVerifyClient optional_no_ca” to “SSLVerifyClient none” and then restart Apache.
  • If there’s an “SSLVerifyDepth 1” line in the conf file, you can remove it by adding the “#” sign before it, for example, “#SSLVerifyDepth 1”.

Checking your SSL/TLS protocol support

While every browser is different, there is a way to go into the settings and make sure that you have support for the latest TLS versions turned on. This is typically done by default, though if you’ve tweaked your settings before that may impact how new features roll out.

Go into your settings and click advanced. Then scroll down to the security settings and open up your SSL/Proxy option.

You want to make sure that you’ve got support for SSL 2.0 and SSL 3.0 turned off, you may also wanted to disable TLS 1.0 and TLS 1.1, as both of those are being phased out, too. You definitely want TLS 1.2 and TLS 1.3 to be supported, as those are the most modern and safest variants of TLS.

Re-Issue your SSL/TLS certificate

For most site owners facing this problem a simple re-issuance and re-installation may fix the problem. Specifically with errors that stem from an incorrect certificate. You can also use this as an opportunity to tweak the TLS versions you’re supporting so that they support the more modern protocols. Unlike browsers, this change typically isn’t made for you server-side, so if you haven’t updated since TLS 1.0 you should probably get to it.

How to Renew an SSL Certificate – The Ultimate Guide

Step-by-step instructions on renewing your website’s SSL certificate.

It is necessary to renew SSL certificates regularly. Usually, SSL certificates need to be renewed or reissued every year. Shortly before the certificate expires, the user starts receiving notifications regarding its expiry. It’s necessary to renew SSL certificates before the expiration to prevent your website from being left unsecured.

Failure to renew SSL certificate in a timely manner will lead to the padlock sign or green address bar being removed from the website’s URL in the browser. Furthermore, Google will flash the “Not Secure” sign, which will deter other viewers from accessing the website, turning traffic away.

In this article, we’ll show you how to renew SSL certificates and answer some pertinent questions about SSL renewal.

How to Renew SSL Certificate And How to Renew Wildcard Certificate

Step 1: First, you must generate a new CSR. The only exception here is if you use an Apache server and if you haven’t changed your business details after purchasing your previous certificate.

Step 2: From your account, you need to select the Renew SSL link.

Step 3: Now select the specific SSL certificate you wish to renew.

Step 4: Your renewal request will be approved shortly. Following that, the certificate will be transferred to your registered email address.

Step 5: Backup the old certificate and then install and verify the new one. Be sure to uninstall the old certificate only after the new one has been verified so your site isn’t left without an SSL.

With these simple steps, you’ll have successfully renewed SSL certificate.

SSL Renewal FAQ

Can the expiration date of a certificate be extended?

All SSL certificates are hard-coded with the expiration date. As such, they cannot be changed. You simply have to “renew” the certificate — which essentially means getting a new certificate while using the same information used previously — and installing that.

When is it ideal to renew SSL certificate?

Users start receiving renewal reminders about 30 days prior to the certificate’s expiration. You should ideally renew the certificate any time before the certificate expires.

You won’t lose any time by renewing early–the certificate authority will add the unused time from your previous certificate to your new certificate.

What do I need to renew an SSL Certificate?

You will need a new CSR for the domain and your user name/password to access your account. If you don’t have username/password for your account, you can re-produce them from here.

Can I re-use my existing CSR or old CSR for SSL certificate renewal?

Some web servers will allow this, but we recommend a new CSR for every renewal.

Do I need to re-validate my company/organization details for EV SSL certificate renewal?

Yes, you need to re-validate your company/organization information If you are renewing an EV SSL certificate. However, in most cases the documents you previously supplied can be re-used for the validation process, so the process is often a lot quicker and easier.

Do I need to install the new SSL certificate after a complete renewal process?

Yes, you need to install the new certificate file on your web server. You cannot modify your previously installed certificate file – you have to install the new file.

If I renew before the expiration date, don’t I lose some of the time I paid for?

Nope! When renewing a certificate ahead of time, you’ll automatically get extra time added to your new certificate to make up for the “lost” time from your old certificate. In fact, you almost always get extra time, so it’s to your benefit to renew early.

As such, it’s beneficial to renew SSL certificates as soon as possible.

Everything you ever wanted to know about Wildcard SSL certificates (SSL certificate for subdomain).

Secure Sockets Layer (SSL) Certificates are crucial for all websites now, both from a security and a visibility standpoint. SSL Certificates serve as cryptographic measures to secure the data being transmitted over a computer network, between a client and server.

And as of last July, Google has also made it mandatory for all websites to carry an SSL certificate. Sites without SSL certificates are flagged as ‘Not Secure’, which can drastically hurt their traffic and prevent them from rising high in Google search results.
