A handshake may be used to welcome someone or seal a deal with them in person; the same is true for the internet.

  • When there is no communication between your computer (the client) and a server, your computer may have encountered a code 1 error or a handshake failed error.

  • A major cause of the code 1 error is an incorrect date and time on the client.

  • Using services like the SSL labs, is a good way to confirm you are running the correct version for SSL and TLS.

  • Easy migration: use the Opera assistant to transfer exiting data, such as bookmarks, passwords, etc.

  • Optimize resource usage: your RAM memory is used more efficiently than in other browsers

An SSL handshake occurs when devices on a network — such as a web server and a browser — discuss keys, encryption methods, and other parameters about their connection before agreeing to transmit data. During a handshake, browsers and servers may request to examine and validate each other’s SSL certificates.

It’s essential to understand what an SSL handshake is and the different ways to resolve errors around it, including the SSL code 1 error. 

How can I fix an SSL code 1 handshake failed error?

1. Correct the date and time on your computer

  • Right-click on the date and time on your taskbar and select adjust date and time.
  • Under the date and time menu, toggle on the option to set time automatically.

Problems associated with the SSL handshake failing might be caused by an incorrect system time and date on your PC. SSL certificates have limited lifespans and will become invalid when they’ve passed their expiry date.

If the time and date on your computer are incorrect, the certificates will always assume the time has elapsed. 

2. Add the website to your allow list

  • Launch Chrome, click on the ellipses button at the top right corner, and select the settings option.
  • Select privacy and security, then click on the option for site settings.
  • Scroll down and expand the Additional content option, then click on insecure content.
  • Click on the Add button in front of Allowed to show insecure content.
  • Input the URL and click add.

Because it’s conceivable that your firewall is producing the SSL handshake failed error by blocking your inspection requests, you should attempt this solution.

Note that adding a website to the allow list may expose you to malware, and you should only try it if you are sure that the website holds no viruses.

3. Verify your SSL Protocol and update your browser

3.1 Verify your browser is using the latest SSL protocol

  • Visit the SSL labs website.
  • Click on projects at the top right.
  • Scroll down and select SSL client test.
  • Under the Protocol Support menu, you will know if the browser has support for the latest SSL/TLS versions.

Note that if you’re experiencing SSL handshake failed errors, and after running this test, you realize that your client (your device) and server don’t support the same SSL version, you’ll need to upgrade your browser.

TLS 1.2 is enabled by default in most recent versions of major browsers, such as Google Chrome.

3.2 Update your browser

  • Launch Chrome, click on the ellipses button at the top right corner, select Help, then About Google Chrome.
  • If there is an update, it will start automatically, and you will have to click relaunch to complete the update.

4. Use an alternative browser

The handshake error is more common in Chrome, and using an alternative browser could help you avoid this error.

While there a many to choose from, we recommend Opera. It is built on Chromium and benefits from its extensive extension library. Opera comes with the added advantage of a VPN that lets you choose servers between the Americas, Asia, and Europe.

It is also compatible across several platforms and will be a great option regardless of your device.

Because an SSL handshake is a critical step in ensuring data security over the internet, this guide has shown steps to resolving your SSL handshake Code 1 error. Now you should be able to create a secure connection between a server and your device.
