How to Fix ERR_SSL_PROTOCOL_ERROR –Step-by-Step Guide

In case your site displays ERR_SSL_PROTOCOL_ERROR, it indicates that it is not accessible in a secure manner anymore. Such an occurrence renders the visitors completely cut off from your site, and the latest browsers, including Google Chrome, Edge, and Firefox, will not allow the page to be accessed in order to protect the users. Consequently, your possible clients leave right away, your bounce rate goes up, and Google might begin to reduce the ranking of your website. Just this one mistake can significantly affect your online business, decrease sales, and ruin your brand’s trust among customers.

 

A secure website is absolutely essential for any business that relies on online visibility, such as e-commerce stores, service websites, or corporate portals. Customers will perceive your site as unsafe if it displays SSL errors, and consequently, they will not submit forms, make payments, or contact you. Therefore, resolving ERR_SSL_PROTOCOL_ERROR is not merely a technical job; rather, it is a business necessity.

 

At Webquick India, a trusted website development and website designing Delhi company, we help businesses solve SSL and website security issues every day. Our team has years of experience in building, managing, and securing business websites across different industries. We understand how SSL, HTTPS, servers, and browsers work together, and we know how to fix errors in the fastest and safest way.

 

What is ERR_SSL_PROTOCOL_ERROR?

 

If a user visits your website, the first thing the browser does is to try to establish a secure HTTPS connection. This connection is secured with SSL (Secure Sockets Layer) or TLS.

 

In case the browser and the website fail to establish the secure connection, the following error is displayed:

 

ERR_SSL_PROTOCOL_ERROR

 

To put it simply:

 

• Your website fails to provide proof of its security.

Thus, the browser prevents access to your website for user protection purposes.

 

Why This Error is Very Dangerous

 

In the event of this error showing up, the problem will be as follows:

 

• People visiting your website will not be able to access it
• Your website will lose its position on Google
• Google Ads will cease to operate
• Transactions over the internet will be unsuccessful
• Trust of customers will be decreased
• There will be a decline in both leads and sales

 

Such a scenario is the reason that web development services and secure website development are so critical in 2026.

 

Main Causes of ERR_SSL_PROTOCOL_ERROR

 

This error happens due to:

 

1. SSL certificate expired
2. SSL certificate missing
3. SSL installed wrongly
4. Website not fully HTTPS
5. Mixed content (HTTP inside HTTPS)
6. Old browser or TLS version
7. Wrong date & time
8. Antivirus blocking SSL
9. DNS or hosting misconfiguration
10. Broken certificate chain

 

These problems usually occur on websites that are not maintained by expert website designing Delhi teams.

 

How to Fix ERR_SSL_PROTOCOL_ERROR (Step-by-Step)

Step 1 – Check SSL Status

Just take it easy and visit your website

 

• Then click on the little padlock icon found in the address bar
• In case it is showing Not Secure, then it means SSL is not working.

 

Another option is to check the SSL status with the help of some online checkers.

 

Step 2 – Install or Renew SSL Certificate

Here you can login to your hosting account.

 

• Then you must check the Security
• SSL section to install
• Renew the SSL certificate.
• Many hosts give out free SSL certs. 
• Allow a 10–30-min activation buffer.

Step 3 – Force HTTPS

 

Your website must use:

 

https://yourwebsite.com

 

In WordPress:

• Settings → General
• Update both URLs to HTTPS

This is a basic rule of modern website development.

 

Step 4 – Remove Mixed Content

 

If your HTTPS site loads any file from HTTP, SSL breaks.

 

Fix using:

 

• Really Simple SSL plugin
• Mixed Content Checker tools

 

Step 5 – Clear Browser & SSL Cache

 

Clear:

• Browser cache
• SSL state

 

Restart browser and test again.

 

Step 6 – Check System Date & Time

Wrong date or time breaks SSL verification.
Correct it and reload website.

 

Step 7 – Update TLS Version

 

Your server must support:

• TLS 1.2
• TLS 1.3

Hosting support or web development service providers can fix this.

 

 

Step 8 -  Antivirus & Firewall

 

Disable antivirus temporarily.

If website opens for that, then move on and change the SSL settings.

 

 

Step 9 – Check Hosting Server

 

If nothing works, SSL chain or server config is broken.
Contact hosting or Webquick India.

 

 

Fixing ERR_SSL_PROTOCOL_ERROR Using Tools

 

Professional website development teams do not guess — they use tools.

Use:

They:
