How to Fix err_ssl_protocol_error on Chrome

The ERR_SSL_PROTOCOL_ERROR in Chrome usually means that the browser is having trouble establishing a secure connection to the website. Here are some steps to fix the issue:

1. Check the Date and Time on Your Device

An incorrect system date and time can prevent Chrome from validating SSL certificates.

On Windows, right-click the clock on the taskbar and choose “Adjust date/time.”
Toggle the “Set time automatically” option to make sure it’s accurate.

2. Clear Browsing Data

Sometimes cached data or cookies can cause this error.

Open Chrome, press Ctrl + Shift + Delete to open the “Clear browsing data” window.
Select “All time” in the Time range.
Check the boxes for Cookies and other site data and Cached images and files.
Click Clear data.

3. Disable Chrome Extensions

Extensions like VPNs or proxies can interfere with secure connections.

Type chrome://extensions in your Chrome address bar.
Disable any extensions you suspect might be causing the issue (especially VPNs or security extensions).

4. Check SSL Settings

You can reset SSL settings to resolve the error.

Type chrome://settings in the address bar, then scroll to the bottom and click Advanced.
Under Privacy and security, click Clear browsing data and clear your SSL state by selecting Cookies and Other site data.

5. Disable QUIC Protocol

Chrome uses the QUIC protocol for faster connections, but it can sometimes trigger SSL issues.

Type chrome://flags/ in the address bar.
Search for QUIC and set Experimental QUIC Protocol to Disabled.

6. Check Your Antivirus Software

Some antivirus programs have SSL scanning that can interfere with Chrome. Try temporarily disabling this feature in your antivirus software’s settings.

7. Update Chrome

Outdated browser versions can sometimes cause connection errors.

Go to the three-dot menu in the upper right corner of Chrome, choose Help, and then About Google Chrome to check for updates.

8. Reset Network Settings

Network configurations could be the cause of the error.

On Windows, open Command Prompt as an administrator and type the following commands:

ipconfig /flushdnsnetsh winsock reset

After running the commands, restart your computer.

Following these steps should help you resolve the ERR_SSL_PROTOCOL_ERROR in Chrome!
