How to Fix Secure Connection Error in WordPress

Are you experiencing a secure connection error on the WordPress website?

Don't worry; you're not alone.

Many website owners encounter this issue, but the good news is that you can fix it easily.

In this blog post, we will explore the reasons behind the secure connection error and provide step-by-step instructions on resolving it.


Understand the Secure Connection Error

When visitors encounter a secure connection error on your WordPress website, their browser cannot establish a secure connection with your server.

It can be due to various reasons, including expired SSL certificates, incorrect SSL configurations, heavy load on the server, or conflicts with plugins or themes.


Check SSL Certificate Expiry


One common cause of a secure connection error is an expired SSL certificate.


To check if this is the case, follow these steps:

  1. Log in to your web hosting account.
  2. Navigate to the SSL/TLS section.
  3. Look for the SSL certificate associated with your WordPress website.
  4. Check the expiration date of the certificate.
  5. If the certificate has expired or is about to expire, you need to renew it.


To renew your SSL certificate, you have a few options:

  1. Contact your web hosting provider: Many hosting providers offer SSL certificate services and can help you renew your certificate.
  2. Use a third-party certificate authority: If you purchased your SSL certificate from a third-party provider, visit their website and follow their instructions for renewal.
  3. Consider Let's Encrypt: Let's Encrypt is a free and open certificate authority that provides SSL certificates. Some web hosts integrate with Let's Encrypt, making obtaining and renewing certificates easy.


If your SSL certificate is valid and up to date, the secure connection error may be due to incorrect SSL configurations.

Here's how you can fix this:

  1. Install the Really Simple SSL plugin: This plugin automatically detects your SSL certificate and configures your WordPress site to use HTTPS.
  2. Activate the plugin and follow the on-screen instructions.
  3. Once the plugin has configured your site for HTTPS, test if the secure connection error is resolved. If not, proceed to the next step.


Website Heavy Load Can Lead to Secure Connection Error


When a website experiences an unusually high traffic volume or is overloaded with data processes, it can strain the server resources. This strain can cause various issues, including the disruption of secure connections.


Server Resource Exhaustion

Each server has limited resources like CPU, memory, and bandwidth.

When a website is overloaded, these resources can be fully utilized, causing the server to respond slowly or not.

If the server is too slow to respond, secure connection handshakes (like SSL/TLS) might time out, leading to the error.


Database Connection Limits

WordPress relies on its database to function.

Heavy traffic can max out the number of allowed connections to the database.

If WordPress can't establish a database connection due to this, it can trigger a secure connection error.


Content Delivery Network (CDN) Overload

Many websites use CDNs to deliver content faster to users across the globe.

However, if the CDN experiences issues or is overloaded, it can cause disruptions, including secure connection errors.


Server Defense Mechanisms

In some cases, if the server detects a rapid spike in traffic, it might interpret this as a Distributed Denial of Service (DDoS) attack.

Some hosting providers have defense mechanisms that might temporarily shut down certain site functionalities to protect. It can inadvertently cause secure connection issues.

To prevent such issues:

  • Optimize the Website: Regularly optimize your WordPress website for performance. It includes optimizing images, using caching mechanisms, and reducing the number of plugins.
  • Upgrade Hosting Plan: If the website consistently gets high traffic, consider upgrading to a hosting plan that offers more resources.
  • Use a Robust CDN: Employ a reliable CDN to handle traffic spikes and distribute the load effectively.
  • Regular Monitoring: Use monitoring tools to monitor website traffic and server health. It can help in identifying and rectifying potential overload issues before they escalate.


Check for Plugin or Theme Conflicts


Conflicts with plugins or themes can also cause a secure connection error.

To identify the culprit, follow these steps:

  1. Deactivate all plugins on your WordPress website.
  2. Check if the secure connection error persists. If it disappears, you know that one of the plugins is causing the issue.
  3. Activate each plugin one by one and test your site after each activation.
  4. If the secure connection error reappears after activating a specific plugin, you have found the culprit. Consider finding an alternative plugin or contacting the plugin developer for support.
  5. If deactivating plugins doesn't resolve the issue, switch to a default WordPress theme and see if the error disappears. If it does, there may be a conflict with your previous theme.


Update WordPress and Plugins

Outdated versions of WordPress or plugins can also lead to a secure connection error.

Ensure you are using the latest versions of WordPress and all installed plugins.

  1. Log in to your WordPress dashboard.
  2. Go to the Updates section.
  3. If updates are available, click the "Update Now" button to update WordPress core files.
  4. After updating WordPress, go to the Plugins section.
  5. Update each plugin individually by clicking on the "Update Now" link below each plugin.


Modify the .htaccess File

Sometimes, editing the .htaccess file can help resolve the secure connection error. Here's what you need to do:

  1. Access your website's files through an FTP client or cPanel file manager.
  2. Locate .htaccess file in the root directory of your WordPress installation.
  3. Download a backup copy of the .htaccess file for safety.
  4. Open the .htaccess file in a text editor.
  5. Add the following code at the beginning of the file:





It is a common method to enforce SSL/TLS security on websites.


Contact Web Hosting Provider

If you have followed all the steps mentioned above and are still experiencing a secure connection error, it's time to contact your web hosting provider.

They will have access to server logs and can investigate the issue further.



A secure connection error on your WordPress website can be frustrating, but you can resolve it quickly with the right troubleshooting steps.

By checking SSL certificates, fixing SSL configurations, identifying plugin or theme conflicts, updating WordPress and plugins, editing the .htaccess file, and contacting your web hosting provider if necessary, you can provide a secure browsing experience for your visitors.

Remember to regularly monitor your SSL certificates and keep everything up to date to avoid future secure connection errors. Happy troubleshooting!
