How to Fix the SSL/TLS Handshake Failed Error?

If you’re not having the right answer to what this SSL error means, then no worries, we’ve got your back. Read further and know what’s this SSL Handshake Failed Error, why it occurs, and how to fix the SSL/TLS Handshake Failed Error.

What Does SSL/TLS Handshake Failed Mean and What Causes It?

The SSL Handshake Failed error occurs when there’s a protocol mismatch. In other words, whenever the client and the server do not have mutual support for the same SSL/TLS version, it shows this SSL/TLS Handshake failed error message.

Once the user sends the secure connection request to the web browser, the browser is expected to send a public key to your computer, which is automatically verified against a list of CAs. And, the computer generates a key and encrypts it with the public key after receiving the certificate.

This SSL/TLS Handshake Failed Error occurs whenever the OS hasn’t granted the read access to the OS, ultimately preventing the complete authentication of the webserver, which indicates that the browser’s connection with the web server is not secure.

Some Reasons That Causes SSL/TLS Handshake Failed Error

Here’s the Client-Side Errors and its Solution

Whenever an SSL/TLS Handshake fails, it’s mostly due to certain things going on with the server, website, and the configuration of its installed SSL/TLS.

Presently the culprit is TLS configuration as support for SSL 3.0 is deprecated. However, there’s a distinct possibility that a client-side error can be the reason behind the SSL/TLS Handshake Failed error. And, some of the common ones are like incorrect system time or browser updates.

Let’s see some of the common causes of SSL Handshake fail error in detail.

1. Incorrect System Time

Not always happen, but sometimes the system clock differs from the actual time. Maybe you did it intentionally, accidental change of settings, or any other reason. It’s a fact that SSL/TLS certificates come with a specific validity period, so the date and time of the system is equally important.

So, the solution is to change the system time and date to correct one, if the system clock is not showing the right time and date. But again, there’s no need to change your system time if it’s correct, as it’s likely that the cause of the error is not the System time.

2. Browser Error

For instance, if you’re using Google Chrome, then try using Mozilla Firefox or any other such as Apple Safari if OS is Mac or else Microsoft Edge for Windows.

However, if you still face the SSL/TLS Handshake Failed error, even after changing the browser, then the issue is not regarding browser but, most probably, the plugin. To verify whether the error can be solved or not, it’s recommended to disable all your installed plugins and reset your browser settings to default.

3. Man-in-the-Middle

Nevertheless, sometimes issues occur with such devices, which causes the SSL Handshake Failure error. And, the reason could be a network firewall preventing the connection or else configuration on an edge device on the server-side network, which means there’s a possibility that this error could be from the client or server-side depending upon the scenario.

Lastly, if the issue is from the client-side, then you can take a chance of exposing yourself by tweaking the settings on your VPN or antivirus. Though, never drop your antivirus or firewall to connect with a website. And, if the server is causing the issue, then mostly configuration is creating an issue on an edge device.

Here’s the Server-Side Errors and Its Solution

Let’s look at some of the common server-side issues.

1. Protocol Mismatch

For instance:

TLS 1.2 came more than a decade ago, and small segments of websites still fail to support it. Earlier back in March 2018, the final version of TLS 1.3 was published as RFC 8446 by the IETF. And, sites were also advised for adding support for TLS 1.3 at their earliest.

So, if the SSL/TLS Handshake Failure error is due to protocol mismatch, it generally means the client and server do not have mutual support for the same TLS version.

For example:

• The client supports TLS 1.0 and TLS 1.1, whereas the server supports TLS 1.2.

As shown in this example, the TLS protocol is not supported mutually. So, it’s likely that the server won’t support backward versions. Nevertheless, the server shouldn’t fix this as well. In this above example, the client must be recommended to upgrade their browser, or else it must be latest with the latest TLS version supported. Presently all we can suggest is that TLS 1.2 or TLS 1.3 must be used, or else support must be added for it.

2. Cipher Suite Mismatch

Nevertheless, Cipher Suites used by TLS 1.3 has been refined. Earlier, Cipher Suite has algorithms that handled:

• Symmetric Session Key Encryption
• Asymmetric Public Key Encryption
• Signature Hashing
• Key Generation

Different Organizations and Government Agencies have different types of encryption standards that suggest different kinds of cipher suites so clients can have different options while being able to find a mutually acceptable cipher. No doubt, it’s less likely that you get a site that only supports a single cipher suite.

Many times, it happens within a network, if you’re doing SSL bridging, where an edge device receives and decrypts HTTPS traffic and then re-encrypts it to send it to the application server. If the application server and edge device fail to share a mutually supported cipher suite, it will cause errors. Similar to Protocol versions, it’s also advisable for cipher suites, to never go backward but only moves forward.

Lastly, a protocol version or cipher suite is deprecated because there’s a vulnerability in that version. So, going back to the earlier version will only make your connection less secure.

What is SSL_ERROR_INTERNAL_ERROR_ALERT?

Don’t worry, I didn’t know what the heck it was either. It kept popping up every time I did anything, on the front end or the back end of my website. A security warning would pop up saying SSL_ERROR_INTERNAL_ERROR_ALERT and I had no idea where it was coming from, and I had no idea how to fix it. Let’s go through what I did to solve this WordPress issue once and for all.

1st Thing’s First

The most likely issue is a plugin conflict of some kind. Read the error message carefully, and see if that gives you any clues as to what might be causing the problem. In this case, it mentions SSL. The problem is, Design Crawl isn’t using SSL. Ok, so the very next thing I do is look at plugins. Usually, 99% of your website problems come from plugin conflicts. These conflicts are common, so there’s really no avoiding them. You just have to address them as they pop up. My Method for determining if any plugins are causing the issue goes like this.

1. I disable any cache plugin I have installed 1st.
2. If that doesn’t solve it, next I disable any other performance or membership plugins.
3. Then, I’ll disable all other plugins at once.
4. If that solves the problem, and the site comes back 100%, I activate plugins 1 by 1 until I receive the error again.
5. That’s how you find the problem child.
6. Then, you can research the problem and find a possible solution, or an alternative plugin.

The Bad News

The bad news is that I disabled all of my plugins, and that didn’t work. Everything I did returned the SSL_ERROR_INTERNAL_ERROR_ALERT message. next, I changed themes. Sometimes themes get updated and no longer play nice with your plugins, or you run into a bug. After changing themes, I still kept getting the SSL_ERROR_INTERNAL_ERROR_ALERT message every time I clicked on something.

Call Support

So, after all of this, I called support, which is Bluehost. If anyone can figure it out, it’s usually Bluehost. They’re always reliable for me, and that’s why I have stuck with them, and why I promote them. They spent almost 2 hours on the phone with me. Unfortunately, we tried everything, and I mean everything to try to resolve the issue. The representative did the best he could, but we were all out of new things to try. We even re-installed a fresh version of the core WordPress files. Still, we couldn’t resolve the issue.

I Never Give Up

That’s part of my personality. I’ve figured out and solved problems for clients, even advanced ones with WordPress that I’d never heard of before, so this was no different. I was determined, so I started doing some research. I kept finding that it mentioned my site was trying to connect to an https page, even though my site was set to http. That was a step in the right direction.

Then, I stumbled upon an article that mentioned how Cloudflare provides free SSL to its customers, even the free ones. Well, with Bluehost, I have Cloudflare for free. Also, I knew that I’d originally set up Design Crawl on Cloudflare, to help it run faster.

The Solution

It turns out, when I went to Cloudflare, there was a setting that had it set to SSL, forcing https where it didn’t apply. Once I disabled Cloudflare, I didn’t receive anymore SSL_ERROR_INTERNAL_ERROR_ALERT messages. I was in the clear! So, if you’re using a CDN, and it has built in SSL support, try disabling it, or try disabling that part of it to correct the issue.
