Update Your Device Time and Date

Hard to believe, right? Well, at times, the simplest tweak solves the severest of problems in tech.

Incorrect date and time might be why you see this site can’t provide a secure connection error.

Browsers are programmed to verify the validity of SSL certificates before loading a site.

This authentication process involves checking the issuance and expiration date of an SSL certificate.

The wrong date might cause this connection error.

The solution here is simple. Set your computer to the current date and time and try accessing the website again.

If you see the error again? try the next fix.

Clear Browsing Data

If the date on your device is correct, It’s time to get rid of browsing data.

Sometimes, cookies cache files when piled up, causing nasty and unexpected errors in your browser, this one inclusive.

Use the steps below to clear browsing data.

Click the menu icon at the top left corner of your browser.

Select Settings from the options.

Go to Privacy and security on the left pane and select Clear browsing data.

Next, check the cookies and cache boxes and click the Clear data button.

Now, load the page again to see if the error is gone.

Clear SSL State on Windows

Still stuck with “this site can’t provide a secure connection” error? the next fix you should try is clearing your device’s SSL state.

The SSL state is a system cache stored and managed by the operating system itself.

It’s not deleted when you clear browsing data. You need to go to your system internet and network settings to delete it.

Here’s how;

Open your computer Search box, type in Control Panel, and select the Best match result.

Next, Go to Network and Internet.

On the next screen, select Internet Options. This will take you to the Internet Properties window.

Once the Internet Properties window opens, switch to the Content tab and Click on Clear SSL State.

Clearing the SSL state will delete all the SSL cache which should now fix the “ERR_SSL_PROTOCOL_ERROR”.

Disable QUIC Protocol

QUIC  is an internet protocol browsers use to establish faster connections by negotiating HTTP parameters with the server.

Although it reduces network latency, QUIC protocol can cause this type of connection issue.

You need to check if QUIC is enabled on your browser and disable it. Here’s how.

Paste chrome://flags/#enable-quic in the Chrome address bar and hit Enter.

You’ll see the Experimental QUIC protocol, at the top of the page. It’s set to Default.

Disable it.

Now relaunch Chrome and try accessing the website again.

Disable Browser Extensions

Extensions are great tools for enhancing the functionality and capability of your browser. But they are not problem-free.

When you’ve tried all the methods above and still see the error, suspect one of your extensions.

To find the culprit, you need to disable and enable all your Chrome extensions one after the other. Here’s how.

Click the menu icon at the top left corner of your screen. Scroll down to More Tools, then select Extensions from the menu that pops up.

Toggle off the button next to each Extension to disable them.

Reload the website again to see if it works.
