How to fix ERR_SSL_PROTOCOL_ERROR

Alright I the found the Fix.

I've been trying to fix my buddy's laptop that gets SLL errors on all browser and all websites. did everything thats posted everywhere and had no luck.

Chat GPT eventually gave me the fix.

Check Services / Background Apps

Run msconfig: (aka system Configuration)

Go to Services

Check Hide Microsoft services

Disable any unfamiliar services (especially security tools, proxies, VPNs)

Also go to Startup tab in Task Manager and disable suspicious entries.

I unchecked these 4 services called: Killer smart AP selection service, KIller Analytics service, Killer Network service, and Killer Dynamic Bandwidth management.

hit apply then restarted pc and it was completely fixed.

If anyone is having this same crazy issue this is 100% the way to fix it. It may not be the same killer service name but look for something not normal. make sure to check Hide Microsoft service to make it easy to find the problem.

Hi. I'm David, and I'm happy to help you.

The ERR_SSL_PROTOCOL_ERROR error in Microsoft Edge usually indicates that the browser was unable to establish a secure connection with the website. This can occur for various reasons, both on the browser's side and the website's side.

Here are some suggestions:

(To avoid a long answer, I won't include everything. So, if none of these help, there are other methods.)

Check your device's date and time.

(SSL certificates rely on correct date and time for validation.)

• Press "Windows + I", select "Time & Language > Date & Time", and enable "Set time automatically".

If the problem persists, clear your browser cache and cookies.

(Old data may interfere with secure connection.)

1. Open "Settings and more (Alt + F)" and select "Settings";
2. In the left panel, select "Privacy, Search and Services";
3. Under "Clear browsing data", click on "Choose what to clear";
4. Under "Time Interval", change to "All time";
5. Leave marked at least "Cookies and other site data" and "Cached images and files";
6. Click on "Clean Now";
7. Close and open your browser.

If the issue persists, temporarily disable all your extensions:

(Some may block or interfere with the SSL connection.)

• Go to Extensions and disable them all. Test the site and re-enable them one by one to identify the culprit.

If the problem persists, please let me know, and I will provide another method.
