Security was not an important issue in the early days of the web. Nevertheless, personal and computer security is becoming more and more important as more information travels online. However, there will occasionally be problems with the procedures we have in place to help. ERR_SSL_PROTOCOL_ERROR may appear in your browser as a result of this.
When a connection should be secure, one endpoint is unable to confirm it—to read between the lines. As a result, the error will be displayed. You may have to look into it further to find the root of the problem, but it might be related to the web server or your browser.
This blog will look at the ERR_SSL_PROTOCOL_ERROR and provide a solution. Before doing this, let's discuss the initial reason for the error and some background information regarding secure connections.
What Is The ERR_SSL_PROTOCOL_ERROR?
You must install a Secure Sockets Layer (SSL) certificate when you build a website. This makes it possible for the website to run over the secure HTTPS protocol.
The safe exchange of data between the user's browser and the server that hosts the website is guaranteed by an SSL certificate. In reality, the browser will most likely display a warning or return an SSL error message such as ERR_SSL_PROTOCOL_ERROR if a site does not have this certificate.
It is possible to run into this issue even if a website is SSL-certified. This can be the result of an out-of-date cache or an unsafe browser extension. Alternatively, the user's device may have a firewall or anti-virus software blocking the connection.
Sometimes the reason for the ERR_SSL_PROTOCOL_ERROR issue is not the user's equipment but rather an issue with the website. For instance, it's possible that the SSL certificate was installed or set incorrectly.
Sometimes the website is still using the HTTP protocol (the less secure version of HTTPS) even when the certificate is correctly installed. Search engines like Google will consider your website dangerous if it uses HTTP instead of HTTPS, which could result in a drop in ranks.
What Triggers The ERR_SSL_PROTOCOL_ERROR?
Encryption technologies like SSL and TLS create an encrypted connection between a browser and a server. They secure private information when it is sent from you to the internet, including passwords, emails, downloads, and more.
The browser and server must handshake with compatible SSL/TLS versions, supported ciphers, and valid certificates in order to establish this encrypted connection. The handshake fails if something interferes with that authentication procedure, leading to browser warnings about connection problems or the dreaded ERR_SSL_PROTOCOL_ERROR.
Among the possible causes of an unsuccessful SSL/TLS handshake are:
How To Fix ERR_SSL_PROTOCOL_ERROR
1. Set The Correct Date & Time
Checking that the date and time on your computer are set correctly is the simplest place to start. Inaccurate information of this kind could interfere with SSL certificate expiration checks and other procedures that rely on synchronized universal timings.
2. Clear Browser Cache & Cookies
Old SSL data from cookies or your browser's cache can interfere with the crucial SSL/TLS handshake. Clearing this data often fixes common SSL problems like the one we're working on right now.
To flush cache/cookies in popular browsers:
Before confirming the clearing, select all time ranges and be sure to check any cached files or images and cookies. After that, try reloading the pages that were originally affected by ERR_SSL_PROTOCOL_ERROR to see if that solves the SSL problem.
3. Update Your Web Browser
Running out-of-date software that is unable to connect using the modern TLS 1.2 or 1.3 protocols that many websites now demand is another browser-based offender. Websites use stronger encryption with every version upgrade to safeguard user data while it's in transit.

However, outdated browsers continue to use outdated protocols, such as TLS 1.0, and fail to support modern ciphers that can establish new server configurations via handshakes. Just update the browser to the most recent version to fix this.
4. Adjust Firewall And Antivirus Settings
Protecting devices and connections from internet dangers is largely dependent on security software, such as firewalls, VPNs, and antivirus programs.
Every now and then, though, people go too far and mistakenly perceive links to trustworthy websites as hazards.
The common ERR_SSL_PROTOCOL_ERROR is raised when this interception stops anything that seems suspicious, causing website connections to fail. Fortunately, this is simple to resolve by including website exceptions in security tools:
Try turning off your antivirus program for a short while as a diagnostic step to see if that fixes the problem. Similarly, you can check if your firewall is the cause of your SSL connection issues by briefly turning it off. Just make sure you turn it back on!
5. Check SSL Certificate Issues
Moving on to non-controllable concerns, server-side website infrastructure is also essential to the successful completion of the TLS handshake with browsers.
A website with SSL protection safely verifies identification and activates encryption. By selecting the padlock icon to the left of the URL in your address bar, you may determine whether the connection you are making to a website is safe.
On the other hand, incorrectly configured or expired certificates may prevent the establishment of secure browser connections and result in the ERR_SSL_PROTOCOL_ERROR error.

Conclusion
You must be safe and secure when using the internet to browse. Websites use an advanced set of technologies that work together to prevent malicious people from accessing your personal data. The ERR_SSL_PROTOCOL_ERROR may appear when the browser and server validation fails in certain situations.
This blog went over the error's solution in several steps. However, the majority of these are related to what an end user may test. This is because improper SSL certificate settings are the cause of server-side problems. However, it's a good idea to double-check everything on your end as well, since there can be a problem you're not aware of.
