How to Fix “ERR_SSL_PROTOCOL_ERROR” For Google Chrome

Read on on how to deal with this.

1. Check the Date of Your System

The most common cause of SSL problems is the date.

The solution is simple: simply set your system's date to the current date and try opening the site again. You will have no problems.

2. Clear Browsing Data

  • Launch Chrome;
  • Press Ctrl + Shift + Delete;
  • Ensure that the time range is set to “All Time”;
  • Check the checkbox for “Cookies and other site data”;
  • Check the checkbox for “Cached images and files”;
  • Hit Clear Data

Wait for it to finish, and then try loading the website again in your browser. There's a good probability it'll open perfectly well.

5. Check Your Antivirus Settings

An SSL error might sometimes be caused by your antivirus software. All modern antivirus applications analyze websites for harmful content and other security issues, including evaluating a site's SSL/TLS version. If a website uses an outdated version of SSL, the antivirus bans it and prevents us from visiting it. In this scenario, momentarily disabling the antivirus can solve the problem. Simply disable your antivirus for a few minutes and see whether you can access the error-generating website.

6. Check Your Firewall

If a website is on your Internet Firewall's blocklist, Chrome will not be able to access it. Check your firewall to make sure the website you're trying to access isn't blocked. Remove it and try loading the website again if you discover it.

7. Disable Extensions

Extensions substantially improve Chrome's functionality, but they can sometimes degrade the internet experience by causing unneeded problems. Disable your Chrome extensions one by one, opening the error-generating page each time. Remove any extensions that you identify to be the culprit.

8. Adjust Your Internet Security and Privacy Level

If everything else fails, the final thing you should attempt is to examine the level of your Internet Security and Privacy, because a privacy level that is too high may also prevent you from accessing specific websites. Take the following steps:

  • Enter "Internet Options" into your computer's search bar and press Enter; the "Internet Properties" dialogue box will appear. Navigate to the Security tab and look at the slider there. If the slider is too much to the right, move it to the middle (to the Medium setting) and click OK.
 Now try to open the website you were attempting to access.

At least one of the options listed above will undoubtedly resolve your ERR SSL PROTOCOL ERR problem with Google Chrome. Try each one until you find the one that works for you.
