How to Fix the Https Not Secure Message in Google Chrome?
To fix “HTTP Not Secure Message”, you need to identify the problem from the above list & fix it to get it solved.
Inaccurate Installation of SSL Certificate:
According to my experience, most of the time people get SSL error for inaccurate installation of SSL certificates.
To avoid error on SSL or HTTPS installation, you need to read the user installation guide properly, before you install the SSL certificate.

Follow all the steps carefully or hire an expert to install the SSL certificate to avoid unwanted hassle on your SSL installation process.
As SSL installation impacts on your website SEO (Search Engine Optimization), you should install it completely error-free.
I provide SSL installation service on different marketplaces, for my clients & readers. If you need SSL installation service, don’t hesitate to contact me through my social profiles or website contact form.
However, if you get an error message on your web browser padlock, you must recheck the installation process and make sure you didn’t miss any step on your HTTPS installation.
Not Activated for Other Properties:
While installing the SSL certificate, you must ensure it’s being installed for all properties like Sub-domains of your website as well.
If you don’t include, other properties like Mail Service, cPanel & Sub-Domains, it won’t work for those services. So, you will get an error message on your web browser padlock.

SSL Installation Missing for Some Properties
This is the common reason most of the website owners do not get green color on their browser padlock. So, you need to install SSL for all the services you want to make it secure.
Your SSL Might Be Expired:
I had a similar heart breaking experience with Name Cheap Hosting though I still love Name Cheap services for their affordable price hosting packages. When I purchased the new hosting plan, they included an SSL certificate for free of cost.
I was so happy & installed the SSL on my all domains.
And I thought it will stay free forever!
But next year, when I renewed the hosting package, my website was working fine, but SSL was not working, because it was issued for 1-year free activation.
However, I got rid of that situation by installing a free SSL certificate from SSLForFree.com.

If you notice “This Connection Is Not Secure” message suddenly, though the SSL was working fine a few days ago, then your SSL might be expired.
You must check the SSL expiry date & renew your SSL certificate.
In case, you are running out of budget to renew the SSL certificate, you can install free SSL certificate following the below tutorial.
Poor SSL Certificate Installed:
The quality of SSL certificates are measured in the bit unit. You will find a range of SSL certificates starting from 256-bit to 2048-bit.

Webmasters experience lower compatibility issue with their SSL certificates when they choose lower bit SSL certificates.
The 2048-bit encryption system provides more security of your sensitive data than the 256-bit encryption.
If you install a lower version of SSL, it won’t able to secure all of your website data and won’t display green padlock on some web browsers.
I use Site Ground Hosting to avoid this hassle, because they provide Free SSL & HTTPS with all the hosting packages. You don’t need to purchase SSL separately & they ensure daily backpack that is essential for website security!
Mixed Content or HTTP Version:
After installing SSL certificate on your website, your first duty is converting all the HTTP links into HTTPS.
Because this is the reason you get the error message “Your Connection to this Site is Not Secure!.”
If you don’t convert all the HTTP link to HTTPS, then your website will not display Secure Message for mixed HTTP contents.
Generally, all the SSL certificates providers have auto HTTP to HTTPS redirection system that will help you converting HTTP link to secure version effortlessly except manual links.
If you have added any HTTP link manually, you have to remove it manually to remove the http error message.

I experienced the same negative issue with my website www.wppathfinder.com.
When I installed SSL on it, it was not working and I was getting red “Your Connection to this Site is Not Secure!” on the web browser padlock.
Because I added the logo link manually and that was holding http:// version.

Holding http:// Version That Should Be Removed
So, you need to make sure that all the HTTP version is updated on your website properly.
I use a simple solution for all my WordPress websites to avoid the mixed content issue. Really Simple SSL WordPress Plugin will fix this issue effortlessly if you have mixed content problem on your website.
You can download the plugins from above link, or you can search “Really Simple SSL” on WordPress plugins directory & install it to get quick solution.
Backdated Web Browser Installed:
If you are using a web browser that is not updated for a long time, then you might experience this problem. Because some older version of web browser can’t read the SSL certificates properly.
So, you have to check the version of your web browser and update it.

Another important thing, you need to wait a few hours after the installation of the SSL on your website. Because it takes some times to update certificate credentials on your website.
According to most of the webmasters, Google Chrome is the most secure & updated web browser that produce fewer compatibility issues. So, I suggest you install Google Chrome Browser for better web surfing experiences.
Harmful Coding on Your Website:
WordPress is the most user-friendly CMS (Content Management System) that has tons of free resources available and millions of developers are pushing it forward.
They are producing both free & paid resources that you can use to develop your excellent websites.
But the problem happens when you can’t identify the harmful resources and install nulled themes with harm codes on your website!
SSL certificates are now more intelligent & easily can identify those codes that work as an obstacle of showing GREEN SECURE PADLOCK on your website.
Sometimes hackers inject harmful codes on websites that is also a reason for showing Not Secure Message on a website.
You need to ensure regular backup to avoid sudden website hack and get rid of this type of situations. I suggest people use Site Ground Hosting because they provide Free SSL & daily backup with all the hosting packages.
Mixed Content Interlinking:
To attain the best SEO value, we often interlink different pages & posts with other posts. This helps to decrease bounce rate & helps in Google Ranking.
I already discussed mixed content or mixed HTTP version that cause the error message or not secure message, even the SSL certificate was installed correctly.

So, we have to go through these two common steps.
- Auto Convert Http:// to Https://
- Manually Update All the Interlinks
You should double check your website pages and posts to identify those mixed contents and fixed them properly.
HTTPS Redirection Not Active:
This is not mandatory with all SSL certificates, but few SSL certificates require this option to activate.

Installing Really Simple SSL will redirect your HTTP versions to HTTPS automatically.
If you are not using WordPress CMS, then you need to find similar plugins, add-ons or service. But SSL certificate provider also provides an option to auto-redirect and avoid mixed contents issue.
You should use this checklist & fix the issues to remove Not Secure Message from your website padlock.
