It might be annoying to see an error notice when surfing the internet, particularly if it stops you from visiting a certain website. ERR_SSL_PROTOCOL_ERROR is one of these errors. Don't worry if you've encountered this mistake. We will look at what the ERR_SSL_PROTOCOL_ERROR is, some of its potential causes, and most importantly, how to repair it. So let's get started and restore the security of your website!


When your web browser has trouble establishing a secure connection with a website, it will display the error message ERR_SSL_PROTOCOL_ERROR. This issue is associated with the SSL (Secure Sockets Layer) or TLS (Transport Layer Security) protocols, which are in charge of encrypting data sent between your browser and the website's server.


  • ERR_SSL_PROTOCOL_ERROR may be brought on by using an out-of-date or unsupported browser. Make sure you are using the most recent version of your browser.
  • Incorrect Date and Time Settings: SSL certificates have expiry dates, and if your device's date and time settings are off, this might prevent certificates from being validated. Check to see whether the time and date on your device are set properly.
  • Interference from firewall or antivirus software: In rare situations, SSL connections might be blocked by firewall or antivirus software, resulting in the ERR_SSL_PROTOCOL_ERROR. The problem could be fixed by momentarily turning off or changing the settings for these security programs.
  • Misconfigured SSL Certificate: The ERR_SSL_PROTOCOL_ERROR might appear if the SSL certificate for the website you are attempting to visit is incorrect configuration. The website's administrator must make sure the certificate is set up and installed correctly.
  • Incompatibility with Older SSL/TLS Versions: You can encounter websites that utilize SSL/TLS that your browser does not support. This problem may be resolved by updating your browser or contacting the website's administrator to enhance security measures.


Let's examine several fixes to the ERR_SSL_PROTOCOL_ERROR and provide a safe surfing experience now that we have determined the potential causes:

1. Updating your browser

Check to see whether your web browser is current to rule out any compatibility concerns. Download and install the most recent version of your browser by going to its official website. After the update, restart your browser and try again to access the website.

2. Verify Date/Time settings

Make sure your device's settings for the date and time are correct. If they are inaccurate, change them to reflect the time and date now. Restart your browser after the settings have been changed, then attempt to visit the website.

3. Short-term Firewall or Antivirus Disable

Disable any installed firewall or antivirus programs for a while, then try to visit the page once again. Make changes to your security software's settings to enable SSL connections if the issue no longer occurs.

4. Delete All Cache and Cookies

Some SSL-related difficulties may be fixed by deleting the cache and cookies in your browser. Go to your browser's settings, look for the choices to clear your cache and cookies, and then delete the items. If the problem still occurs, try restarting the browser.

5. Talk to the site's administrator

Contact the website's administrator and describe the problem in full if you keep getting the ERR_SSL_PROTOCOL_ERROR on a certain website. They should check the settings of the SSL certificate to make sure it is set up properly.


When visiting the web safely, the ERR_SSL_PROTOCOL_ERROR might be a barrier. You may fix the problem and recover access to websites while maintaining your online safety by using the troubleshooting procedures described in this article. The date and time settings should be checked, your browser should be updated, and any security software that can obstruct SSL connections should be adjusted. With these precautions in place, you'll be able to browse the web with ease and confidence in the safety of your surfing.
