Well, you are not the only one experiencing this, there have been various reports from different forums saying that they are having a hard time surfing the internet on their internet browser with a message saying ERR_SSL_PROTOCL_ERROR.

The SSL PROTOCOL error message on your browser simply means that it is having a hard time establishing a secure connection between your computer and the website that you are trying to access. Now, there are different reasons as to why this SSL PROTOCOL error occurs on your computer.

In this case, we decided to create a guide on how to fix the ERR_SSL_PROTOCOL_ERROR message on your browser.

Let’s begin.

Method 1: Restart Your Computer

This method may sound dumb, but a simple restart on your computer or any device can solve a lot of issues. It is possible that your operating system did not load its resources correctly the first time you turn on your computer which causes problems.

To rule out this kind of issue, you can try restarting your computer to allow your operating system to reload all of its system resources.

Step 1. On your computer, press on the Windows key on your keyboard to open the Start menu.

Step 2. Inside the Start Menu click on the Power button to open the selection screen.

Step 3. Finally, click on Restart to begin reloading your system’s resources.

Once your computer has restarted, go back to your browser and try to open a website to see if the SSL Protocol error message would still occur on your computer.

Method 2: Delete the Host File on Your Computer

Windows has a sub file named Hosts which is a text file that has the function to map out website domain names and IP Addresses so that your computer can connect to different sites. However, this file can get corrupted on some occasions which can cause the SSL Protocol error message on your computer.

To fix this, you can delete the Hosts file on your computer so that Windows would generate a version of the file.

Step 1. On your keyboard, press and hold the Windows key + R to open the Run Command Box.

Step 2. Next, type C:WindowsSystem32driversetc and hit Enter to open the folder path.

Method 3: Clear SSL on Windows Settings

When you access a website on your computer for the first time, your system requires a certificate from the website to establish a secure connection to its servers.

Now, this process can slow down the loading times of websites so Windows stores a copy of these certificates so that it won’t require the website the next time you access it.

It is possible that some of the certificates stored on Windows got corrupted which causes the SSL Protocol error message. To fix this, you can try resetting the SSL State on Windows.

Step 1.  Press and hold the Windows Key + R on your keyboard to open the Run Command Box.

Step 2. After that, type inetcpl.cpl and hit Enter to open Internet Properties.
