SSL Handshake Failed Error: What it Is and How to Fix it

In this article, we discuss what an SSL Handshake failed error is and the many different ways you can go about solving it.

What Is an SSL Handshake?

It’s the phenomenon by which your browser proposes a secure connection to an internet server. Sometimes the client, and therefore, the server cannot establish the connection via the protocol. That’s when an SSL handshake failure occurs. This failure often occurs in Apigee Edge. The client, unfortunately, receives the HTTP status 503 with the text “Service Unavailable”.

The fault isn’t yours because companies provide these SSL security certificates. It’s their fault that such errors occur while your browser opens a page.

The error also can come up with a message like, ” Your Connection isn’t Private.” or ” This site certificates aren’t trusted”.

Fixing SSL Handshake Failure

It’s always better to understand why the SSL Handshake Failure occurs. The failure occurs when read access has not been permitted to the OS. As a result, authentication of the web server is banned followed by the opposite steps. The client should immediately get the alert that the browser’s connection to the web server isn’t secure.

The SSL protocol being requested isn’t getting support from the server. This could also be the case because of the cipher suite. It also can happen that the Hostname within the URL doesn’t match with what's on the certificate. The certificate chain may additionally be guilty.

Do check your certificate. There could be a drag with the server also. Maybe it’s unable to attach with the SNI servers.

This could also be said for the client. If the SSL failure is on the client-side, you’ll try a couple of steps to repair the matter on your phone.

Make sure your phone’s date and time are correct. This easy thing might immediately fix your error. Just go to Settings. Select “Date & Time”. Activate the option, “Automatic Date and Time”.

If the above option works, never mind. You’ve got to clear your browsing data now. Open Chrome. Press “Menu”. Go to “Privacy”. Then click on “Settings”. Then click on the ultimate option of “Clear Browsing Data”. Confirm you decide on all the boxes on your screen.

You might even get to change the Wi-Fi connection. Public Wi-Fi is extremely insecure. Immediately turn on to a personal Wi-Fi connection.

The antivirus installed in your mobile could also be creating a drag. Attempt to uninstall it or disable it. Start browsing again. Antiviruses often interfere together with your browser and might cause SSL Handshake Failure.

If the above suggestions don’t work, attempt to reset your device. Simply back up your phone. You would possibly lose all the items that you simply have stored over time. Select Settings. Then click “Backup and Reset”. Then click “Factory Data Reset”.

However, most of the problems are server sided. Chances of them being fixed by the user are low, but it still doesn't hurt to try a couple of things.

Note that the.MNO file, and therefore, the .PQR file has an equivalent prefix. Example: ARTICLE1.MNO and ARTICLE1.PQR — make sure your OS has access to the .PQR file.

Read access is vital for completing the authentication process. Always confirm you’ve got the support for the newest SSL and TLS versions. Meaning, waste no time in turning off SSL 2.0 and SSL 3.0. Also, disable TLS 1.0 and TLS 1.1. of these versions, as they are getting out of date. The foremost modern and therefore, the safest variants of TLS are TLS 1.2 and TLS 1.3.

The Cipher Suite Protocol mismatch is similar to a Protocol Mismatch. The SSL may be a collection of algorithms that serve different functions. Sometimes edge devices receive and decrypt HTTPS traffic. Then, it’s re-encrypted to send along to the appliance server. 

If the sting device and application server shares different supported cipher suites, errors are caused. So always try updating your cipher suites. That’s because older cipher suits tend to be vulnerable and fewer safe.

Always confirm that your certificate chain isn’t incomplete. Certificate Chain remaining incomplete means the browser couldn’t locate one among the intermediates, and therefore, the SSL/TLS handshake has failed.

To remedy this, you need to find and install the missing intermediate certificate, depending on what CA you bought your certificate from; it should have its intermediates available on its website.

The max duration for an SSL/TLS certificate is two years (27 months because CAs will allow you to carry up to three months over from your previous certificate). Eventually, it’s going to be six months. 

That means you need to upgrade your certificates regularly. If you forgot to, that’s probably why the SSL/TLS handshake failed. Just get a legal certificate issued and install it.

If the above options don’t work, follow this last but not the smallest step. It’s probably the safest step. It happens very often that website owners don’t fix their website until it creates an unavoidable problem. That’s because there are only a couple of client-side fixes for the SSL handshake failed error.

Mostly it’s server-side. Your options are limited. The simplest thing to try to is to tell the location owner and await them to repair it. If they don’t, it’d be wise just to stop using the website. There also are certain don’ts to succeed in an internet site:

Don’t drop your firewall.

Don’t disable your antivirus for an extended time. Keep it updated once the browser starts operating.

Don’t ever connect via HTTP.
