Included in the error message is the following information "This site can't provide a secure connection.".

I am using Google Chrome and it will let me load a web site but comes up with the error message if I click on a link. I have tried other browsers but they don't work either.

Hi John,

Google Chrome remains the preferred choice for many Internet users for browsing the web. It is fast and secure but sometimes is known to cause problems. For example, when you try to connect to a website you may receive an error message – This site can’t provide a secure connection and displays the following error code ERR_SSL_PROTOCOL_ERROR.

On most occasions, this error is due to a problem with the server, or it may be requiring a client authentication certificate that might not be available. In addition, the same error could be caused by other several reasons. Nevertheless, here are few solutions that you can try to fix the nagging issue.

To enable users to browse safely on Chrome, Chrome requires websites use trustworthy certificates. A secure website must have trustworthy SSL (Secure Sockets Layer) certificates. In other words, if the website doesn’t have a trustworthy SSL certification on Chrome, you may face this error.
See the URL of the website. If the connection is secure, the address should begin with https (note the s at the end). Alternatively, you can check the security status on the address bar of Chrome. How? To the left of the website address, check the security status. If ‘Secure’ with a lock icon appears on your computer screen, it means the website is secure. Besides ‘Secure’, if you notice ‘Info or not secure’ or ‘Not secure or dangerous’ you should abandon the website immediately.
If you are sure that the website is genuine, proceed to troubleshoot, as follows:

1] Disable Chrome QUIC Protocol
Disabling of QUIC Protocol method in Chrome is one of the tried and tested method to fix SSL error. So if you want to disable QUIC protocol on Google Chrome browser, copy the following address and paste it into the address bar
chrome://flags/#enable-quic” and hit Enter.

Next, select “Disabled” in the drop-down list and then restart your Google Chrome browser. Hereafter, you should stop seeing SSL_PROTOCOL_ERROR in Google Chrome.

2] Configure Correct Date and Time Settings
Sometimes, a change in date and time settings too can cause this conflict. So, it better to configure this setting appropriately
First, type Date and Time settings in the search box and choose this setting. Next, click on “change Date & Time” to change it.
Click on “Time Zone” to change the same.

When done, Press OK.

3] Disable your Internet Browser Extensions
When you face ssl connection error, try launching Google Chrome in Incognito mode and load the same web page with ssl connection error in incognito mode. If you are able to access the webpage, you can be sure that one of your extensions is giving this error. Try to find out the culprit extension and then disable it or remove the extension. To do so, open Google Chrome browser, click on the Menu icon visible at the top right and select ‘More Tools‘ option.
Next, click on the Extensions options there and uncheck the Enabled option marked against the extension you want to disable.
Then, click on Remove to delete it completely.

4] Clear your SSL state
Sometimes the SSL state can unknowingly block the SSL connection. Proceed with these steps to clear your SSL state:
Open Control Panel and click Network and Internet applet in the Category section.
Then, select Network and Sharing Center and choose Internet Options.
Finally, click Clear SSL state in the Content tab and press OK button.

5] Change Your Internet Security And Privacy Level
If you have set the “High” level as your security and privacy level, it might block some unknown connections, including SSL connections. That may result in Err_SSL_Protocol_Error error flashing on your computer screen.
By changing these settings to be “Medium” or “Low”, you can fix this issue and your SSL connections will not be blocked anymore. In order to change your internet security and privacy level, open Control Panel and choose Internet Options.
Next, select the “Security” tab and set “Medium” level.
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 resolved or still persists.

6] Exclude SSL protocol scanning in your Antivirus settings
Sometimes, an Antivirus application can cause unknown problems. So, to fix this, simply go to Setup > Advance setting > Protocol filtering” >“SSL” > ‘Do not scan SSL protocol’. Why do you need to do this? Because at times conflicts between antivirus and encrypted data is inevitable. If this method helps you troubleshoot the problem successfully then, update your browser, your antivirus, and operating system. Also, clear your browser data and try to enable your SSL scanner again.

I hope this helps.
