The err_ssl_protocol_error error message that Windows 10 and Windows 11 users encounter when they want to open a website via the Google Chrome desktop internet browser, as a result of this process failing, is a kind of incompatibility between the website servers to be opened and the client, that is, the user server. When you encounter such an error, the website in question will not open.
What causes the err_ssl_protocol_error error?
When the user wants to open a website via the internet browser, the website in question must present an SSL certificate to the browser under the HTTPS protocol, that is, an identity to prove that it is reliable. In cases where this certificate is not presented, the website in question will not be opened in Google Chrome and similar internet browsers and the user will encounter err_ssl_protocol_error and similar error warnings.
How to solve err_ssl_protocol_error error? Here are the simplest solutions:
- Method #1: Disable plugins that interfere with proxy settings.
- Method #2: Disable your antivirus software.
- Method #3: Clear your internet browser’s cache.
- Method #4: Disable the QUIC protocol.
- Method #5: Update your computer’s date and time.
- Method #6: Contact the website that gave the err_ssl_protocol_error error.
Method #1: Disable plugins that interfere with proxy settings:
All desktop internet browsers offer plug-ins to their users with which they can easily perform many different actions. While these add-ons are sometimes offered to the user by the browser itself through platforms such as the Chrome Web Store, sometimes they need to be downloaded from third-party application stores and installed and used in this way. Pay attention to what settings the plugin interferes with during this installation.
You may be using VPN for a much safer internet experience and you can get this service through an add-on. VPN plugins provide this service by directly interfering with your internet browser’s proxy settings. Different plugins can also interfere with your proxy settings, causing the err_ssl_protocol_error error. If you’re using this type of plugin, disable it and try to reopen the failed website.
Method #2: Disable your antivirus software:
Some antivirus software only scans files that you have downloaded to your computer, blocking potential malware and viruses. Others block malware and viruses that try to infiltrate your computer online, even if you do not download them by scanning your internet browsing instantly. During this blocking, suspicious websites are not opened and errors such as err_ssl_protocol_error may occur.
To resolve the err_ssl_protocol_error error, temporarily disable your antivirus software or switch to an alternative antivirus software. But at this point you have to be careful. The failing site may indeed contain malware or viruses. For this reason, you need to trust your antivirus software when you get an err_ssl_protocol_error error, except for websites you trust. So don’t open that site.
Method #3: Clear your internet browser’s cache:
If you have tried to open the website where you received an err_ssl_protocol_error error before and you have received such an error before, your internet browser cache has saved this error. Maybe there was a temporary SSL certificate error originating from the website servers and this might have been incorrectly saved in your cache.
Even if a website that is saved incorrectly in the cache is corrected, it will continue to give the err_ssl_protocol_error error repeatedly. It is best to clear your cache completely through your internet browser’s settings page. Your browser may run slower for a while after clearing the cache, but at least you won’t get any more errors.
Method #4: Disable the QUIC protocol:
The Google Chrome internet browser uses a protocol called Quick UDP Internet Connections, shortly QUIC, to make the websites you have visited before to be opened much more easily during your re-visit, but this protocol can sometimes cause an err_ssl_protocol_error error.
To disable the QUIC protocol, open your Google Chrome internet browser and go to the address by typing chrome://flags/#enable-quic in the address bar. If you restart the browser after you set the Experimental QUIC Protocol option to Disabled on this page, you will most likely see that the err_ssl_protocol_error error has been resolved.
Method #5: Update your computer’s date and time:
We are in the 21st century, the devices and operating systems we use are now very smart, but unfortunately these are machine-made machines and they can make mistakes. Due to many different reasons, the date and time settings on your computer may be corrupted. The err_ssl_protocol_error error may occur when the date and time of your computer and the date and time of the website server you want to open do not match. You can fix the error by updating the date and time of your computer.
Method #6: Contact the website that gave the err_ssl_protocol_error error:
If you still get the error after using the above methods to resolve the err_ssl_protocol_error error, the problem may not be with you. After all, the reason for this error is that the SSL certificate of the website cannot reach you. The website may be experiencing a temporary problem with the issue, try again after waiting for a while. If you still get the error, contact the website. Maybe the site’s SSL certificates need to be renewed.
We have explained some of the simplest methods you can apply to solve the error by answering questions such as what is the err_ssl_protocol_error error that Windows 10, 11 users encounter in Google Chrome, why it is, how to solve it. If you are not the source of the error, it is better not to trust the website much.
