How to Fix ERR_SSL_PROTOCOL_ERROR
Try the techniques below one by one:
Remove SSL State
If this warning continues disturbing you, you can try erasing your System's SSL state. To achieve it, follow the instructions below:
- Click on the Windows icon
- Type "Internet Options", and a new Internet Properties view will appear
- Click on the Content Tab
- In the Certificate section, click on "Clear SSL State"
- SSL State will be cleared in seconds.
Now, proceed to reopen the web page with Chrome.
Turn off QUIC
Google first created a novel internet protocol called QUIC for their Chrome browser. It is a replacement for the HTTP protocol to enhance performance.
The most recent versions of Chrome have QUIC enabled by default, but you may turn it off from the options panel. Disabling QUIC will force the browser to use HTTP instead for those with connection issues.
QUIC could be turned off in Chrome by entering chrome://flags/#enable-quic:
- Click the dropdown menu next to Experimental QUIC Protocol
- Select Disabled.
- Click the Relaunch button, which is at the bottom of the page.
- Return to the website you are trying to load and check whether the protocol challenge is still there.
Delete Browsing Data
Sometimes, browsing data may also get in the way of your internet browsing, causing you to get that annoying SSL error. Follow the instructions below to remove browsing history from your Chrome browser if your computer's date is accurate:
- Ctrl + Shift + Delete when using Chrome.
- Ensure "All Time" is selected as the time range.
- "Cookies and other site data" should be checked in the checkbox.
- Check the "Cached images and files" checkbox.
- Click on Clear Data.
Please wait for it to finish, then attempt to reload the webpage in your Browser when it is completed. There is an excellent possibility that it will open without any issues.
Check System Date
The most common cause of SSL failures is the date. Your Chrome browser will display this error when the dates on your computer and the server you're attempting to access are out of sync. Change your system's date to the current date to rectify the issue, and then try reassessing the website. You won't run across any problems.
Turn off Antivirus Software and Third-Party Extensions for the Browser
Extensions are a great approach to increasing the functionality of your browser. These extensions can often interfere with protocol settings.
Visit your extensions page by selecting More Tools > Extensions from the Chrome menu to see any possible extensions causing issues.
Turn off all your extensions. Then, go back to the webpage where the issue appeared. You may conclude that an extension is at fault if it disappears.
The next step is activating each extension and refreshing the page between each one. You can start looking for a solution when you've identified who the criminal is. Disabling any installed firewalls or antivirus programs is also a brilliant idea.
