Your Connection is Not Private SSL Error in WordPress

Introduction

Your Connection is Not Private is a common SSL-related warning that WordPress website owners may see when visiting a website through HTTPS. Instead of loading normally, the browser may display a warning such as “Your connection is not private” and prevent visitors from accessing the website.

This problem can be caused by an expired SSL certificate, incorrect HTTPS settings, mixed content, incorrect website URLs, server configuration, browser cache, or a CDN such as Cloudflare.

In this guide, you’ll learn 9 easy ways to fix Your Connection is Not Private in WordPress. We’ll start with the simplest solutions and then move toward SSL, WordPress, hosting, and Cloudflare troubleshooting.

What Does “Your Connection is Not Private” Mean?

When you visit a website using HTTPS, your browser expects the website to have a valid SSL/TLS certificate.

The certificate helps establish a secure connection between the visitor’s browser and the website server.

If the browser cannot verify the certificate, it may show:

Your connection is not private

You may also see browser-specific error codes such as:

NET::ERR_CERT_COMMON_NAME_INVALID
NET::ERR_CERT_DATE_INVALID
NET::ERR_CERT_AUTHORITY_INVALID

These messages can look alarming, but they do not always mean your WordPress website has been hacked.

In many cases, the problem is simply an SSL configuration issue.

Why Does Your Connection is Not Private Appear in WordPress?

Several different problems can trigger the warning.

Common causes include:

  • Expired SSL certificate
  • SSL certificate installed incorrectly
  • Domain does not match the certificate
  • WordPress still uses HTTP
  • Incorrect WordPress Address URL
  • Mixed content
  • Cloudflare SSL configuration
  • Incorrect server configuration
  • Browser cache or certificate cache
  • Incorrect website date and time

If the warning appears on your own website, start with the simplest checks before changing advanced server settings.

Before Fixing the SSL Error

Before making changes to WordPress or your hosting account, create a complete backup.

A backup protects your website if you accidentally change an important configuration file.

Your backup should include:

  • WordPress database
  • Website files
  • Themes
  • Plugins
  • Media files
  • wp-config.php
  • .htaccess

Also note whether the problem started after:

  • Installing an SSL certificate
  • Changing your domain
  • Moving hosting providers
  • Enabling Cloudflare
  • Installing a security plugin
  • Changing WordPress URLs
  • Migrating your website

This information can help you find the cause faster.

Fix 1: Check Whether Your SSL Certificate Has Expired

The first thing to check when Your Connection is Not Private appears is the SSL certificate.

An SSL certificate has a validity period. Once it expires, browsers may stop trusting the HTTPS connection.

How to Check Your SSL Certificate

Open your website in a browser.

Click the security icon next to the website address.

Depending on your browser, you may see information about the site’s connection and certificate.

You can also check your SSL certificate through your hosting control panel.

If you’re using managed hosting, look for a section such as:

SSL → SSL Certificates

Check:

  • Certificate status
  • Expiration date
  • Domain name
  • Installation status

If the certificate has expired, renew or reinstall it through your hosting provider.

Many modern hosting providers offer free SSL certificates, but the exact renewal process depends on the host.

Fix 2: Make Sure Your WordPress URLs Use HTTPS

Incorrect WordPress URLs are another common cause of SSL problems.

Go to:

WordPress Dashboard → Settings → General

Check:

WordPress Address (URL)

and:

Site Address (URL)

If your website uses HTTPS, they should normally use:

https://yourdomain.com

instead of:

http://yourdomain.com

For example:

WordPress Address:
https://yourdomain.com

Site Address:
https://yourdomain.com

Save the changes if necessary.

Then open your website in a private/incognito browser window.

If you cannot access the WordPress dashboard, your website URLs may also be controlled through wp-config.php.

Fix 3: Force HTTPS Correctly

If your SSL certificate is valid but visitors are still being sent to HTTP, your website may need to redirect HTTP traffic to HTTPS.

The desired setup is:

http://yourdomain.com
        ↓
https://yourdomain.com

You should not create multiple competing redirect rules.

If you’re using a security plugin, hosting redirect, Cloudflare, and .htaccess at the same time, they may conflict.

Check your existing HTTPS configuration before adding another redirect.

If your hosting provider already forces HTTPS, you may not need an additional WordPress plugin.

Fix 4: Check for Mixed Content

Mixed content happens when your main website loads over HTTPS but some resources still use HTTP.

For example:

https://yourdomain.com

but an image or stylesheet loads from:

http://yourdomain.com/image.jpg

This can create security warnings or cause some website resources to load incorrectly.

Common Sources of Mixed Content

Check for HTTP URLs in:

  • Images
  • CSS files
  • JavaScript
  • Theme files
  • Plugin settings
  • Widgets
  • Database content
  • Custom HTML
  • Old internal links

Search your WordPress content for:

http://yourdomain.com

and replace appropriate URLs with:

https://yourdomain.com

Do not blindly replace every HTTP URL in your database. Create a backup first and use a reliable search-and-replace method.

Fix 5: Clear Your Browser Cache and Test Incognito Mode

Sometimes the SSL problem has already been fixed, but your browser continues showing an old certificate or redirect response.

Open your website using:

Incognito / Private Browsing

If the website works there, your normal browser may have cached old information.

Try:

  • Clearing browser cache
  • Clearing cookies for your domain
  • Closing and reopening the browser
  • Testing another browser
  • Testing another device

You can also perform a hard refresh.

Windows

Ctrl + F5

Mac

Command + Shift + R

If Your Connection is Not Private appears on every browser and device, the problem is more likely related to the website or server.

Fix 6: Check Your Domain Name and SSL Certificate

Your SSL certificate must cover the domain visitors are accessing.

For example, these can be different:

yourdomain.com

and:

www.yourdomain.com

If your certificate only covers one version, the other version may generate a certificate warning.

Check whether your SSL certificate supports:

  • Root domain
  • www version
  • Any required subdomains

Also check that your domain’s DNS records point to the correct server.

If you recently moved your website to another host, DNS changes may take some time to propagate.

Do not repeatedly reinstall SSL certificates while DNS is still pointing to the wrong server.

Fix 7: Check Cloudflare SSL/TLS Settings

If your website uses Cloudflare, check the SSL/TLS configuration.

Go to your Cloudflare dashboard and open:

SSL/TLS → Overview

Cloudflare provides different SSL modes, including:

  • Off
  • Flexible
  • Full
  • Full (strict)

Your selected mode should match the SSL configuration on your origin server.

For example, if your hosting server has a valid SSL certificate, Full or Full (strict) may be appropriate depending on your setup.

A mismatch can cause:

Browser
   ↓ HTTPS
Cloudflare
   ↓ HTTP
Origin Server
   ↓ HTTPS redirect
Cloudflare

This type of configuration can create HTTPS problems and redirect loops.

If you are unsure which mode to use, ask your hosting provider to confirm the SSL configuration on the origin server.

Fix 8: Check Your Hosting SSL Configuration

If the previous fixes don’t work, the problem may be on the hosting server.

Open your hosting control panel and check the SSL section.

Look for:

  • SSL certificate status
  • Domain coverage
  • Certificate expiration
  • HTTPS status
  • AutoSSL status
  • Redirect settings

If your hosting provider manages SSL automatically, contact support and ask them to verify the certificate installation.

Tell them the exact browser error you’re seeing.

For example:

NET::ERR_CERT_DATE_INVALID

or:

NET::ERR_CERT_COMMON_NAME_INVALID

The specific error code can help the hosting provider identify the problem.

Fix 9: Check Your Computer’s Date and Time

This simple fix is often overlooked.

If your computer’s date or time is significantly incorrect, your browser may have trouble validating SSL certificates.

Check your operating system’s:

  • Date
  • Time
  • Time zone
  • Automatic time synchronization

Set the correct date and time.

Then restart your browser and test the website again.

This is especially useful if the SSL warning appears on only one computer while the website works normally for everyone else.

Check WordPress After Fixing the SSL Error

After making changes, test more than just the homepage.

Open:

https://yourdomain.com

Then test:

https://yourdomain.com/about/
https://yourdomain.com/blog/
https://yourdomain.com/contact/

Also check:

  • WordPress login
  • Images
  • CSS
  • JavaScript
  • Contact forms
  • Mobile version
  • Internal links

Make sure there are no unexpected HTTP URLs remaining.

Check HTTPS SSL configuration to fix Your Connection is Not Private

What If Your Website Still Shows the SSL Warning?

If Your Connection is Not Private continues appearing after the basic fixes, investigate the advanced configuration.

Check:

  • SSL certificate chain
  • DNS records
  • Cloudflare settings
  • Server configuration
  • Redirect rules
  • WordPress URL settings
  • Mixed content
  • Domain aliases
  • Hosting SSL configuration

If you’re not comfortable changing server or SSL settings, contact your hosting provider.

Avoid repeatedly changing SSL settings without knowing which service currently controls HTTPS.

How SSL Helps Secure Your WordPress Website

HTTPS is an important part of website security.

A properly configured SSL/TLS connection helps protect data transmitted between visitors and your website.

This is particularly important for websites handling:

  • Login credentials
  • Contact forms
  • Customer information
  • Checkout information
  • Membership accounts

However, SSL alone does not completely secure WordPress.

To Secure Your WordPress Site, you should also:

  • Keep WordPress updated
  • Update plugins and themes
  • Use strong passwords
  • Enable two-factor authentication
  • Remove unused plugins
  • Create regular backups
  • Use trusted themes and plugins
  • Monitor administrator accounts

A valid SSL certificate helps protect the connection, but it does not prevent a hacker from exploiting an outdated plugin or weak password.

Common WordPress SSL Errors

The Your Connection is Not Private warning is only one type of SSL-related problem.

You may also encounter:

  • SSL certificate expired
  • SSL certificate mismatch
  • Too many redirects
  • HTTPS not working
  • Mixed content warnings
  • ERR_CERT_DATE_INVALID
  • ERR_CERT_COMMON_NAME_INVALID
  • ERR_SSL_PROTOCOL_ERROR

Common Mistakes to Avoid

Avoid these mistakes when fixing Your Connection is Not Private:

  • Installing multiple SSL plugins without understanding their settings.
  • Using Cloudflare SSL settings that conflict with your hosting server.
  • Adding multiple HTTPS redirect rules.
  • Ignoring an expired SSL certificate.
  • Forgetting to check the www version of your domain.
  • Replacing HTTP URLs without creating a backup.
  • Changing DNS records randomly.
  • Testing only the homepage.
  • Ignoring mixed content.
  • Assuming an SSL warning automatically means a hacker attacked your website.

Make one change at a time and test the website after each change.
