Methods To Fix Err_SSL_Protocol_Error On Google Chrome

If you search on Google how to fix Err_SSL_Protocol_Error, it will return to you a lot of results, and you need to read all of those articles and try all methods listed there. To make this process simpler and help you solve the issue quicker, I have collected and created this guide, which contains some useful methods you should try.

Verify Your Computer’s Date And Time Is Correct

Like the Your Connection Is Not Private error if the date and time of your PC or device are incorrect, your browser can’t load SSL connections properly.

Before going further, you need to check your computer’s date and time again ensures it’s correct and match with the current time.

Computer Date And Time

Temporarily Turn Off Antivirus And Internet Security Apps

Sometimes, your antivirus software, internet security programs or built-in firewall blocks SSL connections. That made all of SSL connections can’t load completely and lead to this error.

To diagnose this issue, temporarily disable your antivirus software, internet security programs, firewall or anything similar. If the error is gone, you can figure out the cause of the Err_SSL_Protocol_Error error.

Kaspersky Pause Protection

Remove System Hosts File Or Restore It To Default

If some program modified your hosts file, or it was affected by viruses or malicious programs, you may face this SSL error on your Google Chrome browser. In this situation, your hosts file may contain incorrect information and will redirect the Internet connections to wrong places. That could be a reason why this SSL error showed up as SSL certificates can’t verify SSL connections.

So, if you are not using your hosts file for any purpose, simply remove it from this location: “C:\Windows\System32\drivers\etc\“.

The Windows hosts file

If you are unable to remove the hosts file, make sure you have permission to do that. In order to grant permission for your current user, right-click on the hosts file and choose “Properties”.

After that, click on the “Security” tab and choose “Edit” button. Next step, select the username you are using and checked all in the “Allow” column.

Delete or remove Windows hosts file

If you are using the hosts file for some reasons and have declared your commands there, just keep your code and remove the unusual one.

Clear SSL State To Fix Err_SSL_Protocol_Error Error

In some cases, SSL state may block your connection and show you this error. By that, you have to remove all SSL state.

To clear SSL state, go to Control Panel and select Internet Options.

Windows 10 Internet Options

Next, select the “Content” tab and click on the “Clear SSL state” button and then click “OK”.

All is done. You may want to try to reload your website on Google Chrome browser again to verify if the error is gone or not.

Change Your Internet Security And Privacy Level

If you have set the “High” level as your security and privacy level, it might block some strange connections, including SSL connections. That resulted in Err_SSL_Protocol_Error error.

By changing these settings to be “Medium” or “Low”, your SSL connections will not be blocked anymore. In order to change your internet security and privacy level, go to Control Panel and choose Internet Options.

Next, select the “Security” tab and set “Medium” level.

Change Security Level In Internet Options

Do the same with the “Privacy” tab. After changing these settings, try to reload your Google Chrome browser again to confirm if the issue is gone or remains.

Disable Chrome QUIC Protocol To Fix Err_SSL_Protocol_Error

According to reports, there were many users used this method and it was helped to solve the problem. So if you want to disable QUIC protocol on Google Chrome browser, copy “chrome://flags/#enable-quic” and paste it into the address bar and press “Enter”.

Next, select “Disabled” in the drop-down list and then restart your Google Chrome browser.

    I have tried everything suggested on this page and still encountering the err_ssl_protocol_error on Chrome.
    The last resort which got things working is to remove the “Chrome” folder in AppData.

    \AppData\Local\Chrome

    Hope this information helps those in the same situation that got me stuck for 2 days.
