7 solutions to fix the err_connection_aborted Chrome browser error

We’ll start with the simplest solutions first and then work towards more time-consuming options if the simple solutions don’t work. Each solution contains a short introduction and background before walking you through the solution step by step. Let’s get started with fixing the err_connection_aborted error.

1. Disable SSLv3 and use the TLS protocol

SSLv3 stands for Secure Socket Layer version 3. SSLv3 is a security protocol for application protocols like HTTP, SMTP, and more. SSLv3 is outdated and has known security vulnerabilities. In September 2014, Google discovered a serious vulnerability in SSLv3, called POODLE. A POODLE attack can allow a malicious actor to steal your passwords. A security protocol that allows encrypted information to be stolen isn’t much of an effective security protocol at all. 

Since this discovery, browsers and websites have largely moved away from the SSLv3 protocol and switched over to the more secure TLS 1.0 protocol. Even though TLS1.0 is outdated at this point, it is not known to have a critical flaw like SSLv3. 

TLS 1.0 and TLS 1.1 were deprecated at the end of 2020, and most organizations and websites have since moved on to TLS 1.2 or the most current protocol, TLS 1.3.

If a website has disallowed the use of SSLv3, but your Chrome browser has it enabled, you might experience the err_connection_aborted issue when trying to load the site. To fix this issue, you can disable SSLv3 within your Chrome browser:

  1. Press the Windows key or Start to open Windows Search. Type “Google Chrome” into the search bar. Then right-click on the Google Chrome app icon and select Open file location
