    Restart Chrome and see whether this has had any effects or not. If not, try the next one!

    If the SSL State is not cleared, it might block SSL connection and cause the SSL Connection Error. Follow the steps below to clear the SSL state.

    How to Fix ‘ERR_SSL_PROTOCOL_ERROR’ on Google Chrome

    A quick guide on how to fix Chrome’s ‘This site can’t provide a secure connection’ or ‘ERR_SSL_PROTOCOL_ERROR.’

    If Google Chrome is your window to the world of the internet, you must have encountered “This site can’t provide a secure connection” or ERR_SSL_PROTOCOL_ERROR message at least once. The thing about this error is that there’s no particular pattern behind it. It can pop up on the most popular sites as well as on the least ones. Heck, I’ve gotten it on here, on our website, and I can assure you our SSL is up to snuff.

    As far as the reason that Google sometimes says “This site can’t provide a secure connection” is concerned, it’s almost impossible to pin it down to a single cause. From an issue as trivial as an incorrect date to a perplexing server issue – it could be anything.

    Let’s leave the diagnostic part aside for a moment and focus on what you’re here for – the treatment.

    Here’s a quick, troubleshooting guide to fix ERR_SSL_PROTOCOL_ERROR on Google Chrome. If one doesn’t work, try the next one. Sooner or later, you should get rid of this issue.


    Fix ERR_SSL_PROTOCOL_ERROR by setting the correct Date & Time
    Sounds too obvious, doesn’t it? Well, most of the time, the simplest solution to a problem is the correct one. In this case, incorrect date & time settings might be causing trouble for you. So, make sure that your system isn’t lagging behind or running ahead.

    Fix ERR_SSL_PROTOCOL_ERROR by clearing Chrome’s Browsing Data
    From one obvious solution to another.

    If you already have the correct date & time, it’s time to clear Chrome’s cache and cookies. To do so, press Ctrl + Shift + Delete and erase your browsing data. Even if this hasn’t fixed the “This site can’t provide a secure connection” error, we recommend clearing your browsing data on a regular basis.

    Fix ERR_SSL_PROTOCOL_ERROR by clearing your SSL State
    If neither of the above works, clearing your SSL State is the next thing you should try. Follow the steps below to do so:

    1. First, go to Customize and control Google Chrome, the three dots you see just below the X (close) button.
    2. Now click on Settings.
    3. Scroll down the page and open the Advanced Settings.
    4. Go to Open proxy settings by scrolling down or searching in the search bar.
    5. A window named ‘Internet Properties’ will open up.
    6. Go to the Content window and click on the Clear SSL State Button.
    Fix ERR_SSL_PROTOCOL_ERROR by disabling QUIC Protocol
    QUIC (Quick UDP Internet Connections) provides a TLS/SSL equivalent connection to Google’s servers. By default, the QUIC protocol is enabled in Chrome. To disable it, copychrome://flags/#enable-quic and paste it into the address bar, hit enter. On top of your screen, theExperimental QUIC Protocol would have been set as Default. Disable it and relaunch Chrome.

    Fix ERR_SSL_PROTOCOL_ERROR by checking your Antivirus Settings
    Warning: This step isn’t entirely safe as it allows the older, insecure SSL/TLS protocols that some of the websites still use.

    You might not know this, but your Antivirus software keeps an eye on the web pages you visit and protects you against any threats they may pose or contain. It does this by checking the SSL/TLS protocol a website uses. Upon finding the protocol to be unsafe and outdated, it prevents you from visiting the site.

    There isn’t any one particular way to change the settings for all Antivirus software as the UI and settings differ from one software to another. You’d have to find and see if it’s scanning the SSL protocols. If it does, disable it and see what happens. If the problem persists, revert to the original settings.

    Fix ERR_SSL_PROTOCOL_ERROR by Enabling all SSL/TLS Versions – The Last Resort
    Warning: This step isn’t entirely safe as it allows the older, insecure SSL/TLS protocols that some of the websites still use.

    When you visit an SSL-enabled website, it uses SSL/TLS protocols to communicate with the server. Sometimes, the SSL/TLS version of a website might not be compatible with your Chrome as Chrome doesn’t permit deprecated SSL/TLS protocols to run by default. Therefore, you’d need to change those SSL/TLS protocol settings. Here’s how you can do it:

    1. Click on the three dots you see in the top-right corner of Chrome and click on Settings.
    2. Now scroll down and go to Advanced Settings.
    3. Find the Proxy settings and open it.
    4. Click on Advanced
    5. Scroll down till the Security section comes up. Now make sure that you have checked all SSL and TLS versions.
    6. Click Apply.
    7. Relaunch your Chrome.
    We hope that this guide has helped you fix ERR_SSL_PROTOCOL_ERROR or “This site can’t provide a secure connection” messages on Chrome. And if it doesn’t, share your concerns in the comments section and we’ll try to help you out with it.
