More than 80% of websites worldwide run on HTTPS security. Yet, more often than not, internet forums are flooded with questions regarding the “This site can’t provide a secure connection” error. 

The problem tends to affect local environments like MAMP for WordPress hosting. The problem usually stems from browser settings or SSL certificate issues. You can typically resolve it by clearing your browser cache. Alternatively, you might need to generate an SSL certificate for localhost. Understanding the underlying cause helps you fix the error quickly. 

In this blog, we’ll help you understand, diagnose, and eventually resolve this basic yet most common connectivity issue.

Understanding the ‘This Site Can’t Provide a Secure Connection’ Error

The “This site can’t provide a secure connection” error means that your browser failed to establish a secure HTTPS connection. Most occurrences of the issue are attributed to some problems with your browser’s website SSL certificates or security settings. Although it doesn’t always mean the site is unsafe, it can point to some other underlying connectivity problems.

For local environments like MAMP used in WordPress hosting, the error is common. It often appears because these setups lack proper SSL certificates by default. You might see slight variations of the message on other browsers, but all pinpoint the same issue.

Primary causes of the error include: 

  • invalid or expired SSL certificates, 
  • outdated browser caches, or 
  • wrong system time settings. 

Knowing the cause will assist in troubleshooting effectively. Only by understanding the root cause can you work your way through resolving it.

Common Causes of the Error – This Site Can’t Provide a Secure Connection

Understanding the error is just the first step. To effectively resolve the issue, you need to identify what causes the issue. Below are some of the common causes:

1. Missing SSL Certificate

Local environments like MAMP often lack SSL certificates by default. It is a frequent issue when setting up WordPress hosting sites for testing. Without a valid certificate, your browser can’t establish a secure connection.

Generating a self-signed certificate for localhost can resolve it but requires some technical knowledge.

2. Outdated Browser Cache

Your browser stores SSL certificates in its cache to speed up browsing. If the site’s certificate changes but your browser loads an old cached version, it triggers the error. Clearing your browser cache often resolves the issue. 

However, frequent cache clearing can slow down your browsing experience. It’s a balance between security and convenience.

3. Incorrect System Time

In case the settings for time and date on your computer are wrong, it might cause problems with the authentication of SSL certificates. The reason is fairly simple: certificates have limited validity periods. 

Make sure that your system time is correct to avoid the issue. Syncing your system time with an internet time server can prevent the problem from recurring.

4. Expired or Invalid SSL Certificate

SSL certificates are to be renewed periodically. The error may appear if your certificate is either expired or invalid. Regular auditing of the status of your SSL certificates can avoid unexpected expiration while keeping it secure from hackers.

At WeWP, we have years of expertise in providing managed WordPress website hosting services. We always ensure timely certificate renewals for our clients.

5. Antivirus Software False Positives

Some antivirus programs that scan connections in real time can trigger false positives. It might lead to a secure connection error, even on safe sites. Adjusting your antivirus settings can help.

Although, you must be cautious when modifying security settings. It could potentially leave your system vulnerable to actual threats.

6. Rogue Browser Extensions

Faulty or misconfigured extensions can cause secure connection failures within a browser. It might be because of coding errors or, very rarely, even due to malicious intent. Disable suspicious extensions and find out which one is the bad actor.

Regularly reviewing and updating your browser extensions can prevent such issues. It also enhances overall browsing security.

7. Network Interference

In some cases, network settings or firewalls can block secure connections. It is more common on public or restricted networks. If you’re using cloud hosting solutions, ensure your network allows necessary connections.

Using a VPN might bypass network restrictions, but be aware of any legal or policy implications in your specific context.

How Does ‘This Site Can’t Provide a Secure Connection’ Warning Impact Your Website

For website owners, a “This Site Can’t Provide a Secure Connection” warning isn’t a mere inconveniencing factor. It can dent your website’s performance and reputation in so many ways:

  1. User Confidence and Trust: Such a warning will immediately put off a visitor to your website. It will give them a feeling of insecurity, hence pulling them back from further action. It may lead to increased bounce rates and low user engagement.
  2. Search Engine Rankings: Search engines prioritize secure websites for SERP rankings. Your site will show warnings, which may impact your search engine optimization efforts. Your website will gradually start ranking lower and, hurting the organic traffic that is coming to the website.
  3. Conversion Rates: If the browser tags a website as insecure, users are less likely to fill in sensitive information. It can significantly affect your conversion rates and efforts, impacting newsletter signups, sales, form submissions, or other on-site activities. You’ll be hit on the bottom line with lost leads or sales.
  4. Brand Reputation: Frequent security warnings, when received in succession over a long period, is damaging to your brand’s reputation. It gives out the impression that your website is either unreliable is harmful, hence killing its credibility. Such a negative perception doesn’t stop at the website front — it affects the whole brand’s face or business.
  5. Legal and Compliance Issues: Depending on your industry, failing to provide a secure connection could lead to legal issues. Many regulations require secure handling of user data, and the warning indicates a potential breach. Non-compliance could result in fines or legal action against your website or business.

Note: To mitigate these risks, opt for managed WordPress website hosting services from reputed providers like WeWP. We also provide cloud hosting solutions for enhanced website security and SSL management, especially for WordPress hosting sites.

How to Diagnose the ‘This Site Can’t Provide a Secure Connection’ Error?

Step 1: Check Multiple Browsers 

Open your website in Chrome, Firefox, and Safari. If you see the error on all of them, most likely, it’s a server-side issue. If it shows up only in one, then maybe there’s something wrong with your particular browser’s cache or settings.

Step 2: Verify the SSL Certificate 

Inspect your site’s SSL certificate by clicking on the padlock icon in the address bar. Check if the certificate is valid and hasn’t expired. For WordPress hosting sites, ensure your hosting provider has properly installed the SSL certificate.

Step 3: Test on Different Devices and Networks 

Try to access your site using different devices and networks. If the error persists for all, then the issue is from the server side. If network-specific, then the problem is with your local network settings.

Step 4: Check Your Computer’s Date and Time 

Ensure your system’s date and time are correct. Incorrect settings can cause SSL validation failures, leading to secure connection errors.

Step 5: Disable Browser Extensions 

Temporarily disable all browser extensions and try accessing your site again. If the error disappears, re-enable extensions one by one to identify the problematic one.

Step 6: Flush Stored Browser Cache and Cookies 

Clear out years of unflushed browser cache/cookies. It may resolve issues caused by using out-of-date/corrupted local data, particularly in case you have recently changed your SSL certificate.

Step 7: Check for Mixed Content 

Inspect your website’s source code for any resources (like images or scripts) loaded over HTTP instead of HTTPS. Mixed content can trigger security warnings.

Step 8: Verify Server Configuration 

If you’re using cloud hosting solutions, check the configuration of your server’s SSL. Ensure that your server is properly set up to handle HTTPS connections. Ensure all the necessary ports are open.

If all of the above seems like a hassle, get in touch with WeWP. From WordPress hosting to professional consultations —  we provide 24/7 service and everything in between!

Fixing the Error – This Site Can’t Provide a Secure Connection

Yes, updates to your SSL and browser settings do help avoid the “secure connection” issue. But what if the reason is something entirely else? 

Don’t worry. 

Below are some less commonly talked-about fixes for the connectivity error:

  • Inspect your CDN settings if you’re using one for content delivery. Misconfigured CDN SSL settings can lead to secure connection warnings for some users.
  • Check the OCSP (Online Certificate Status Protocol) stapling configuration of your server. A well-functioning OCSP stapling can reduce the SSL handshake time and increase server stability.
  • Activate HSTS (HTTP Strict Transport Security) for your server. It ensures your site always uses HTTPS, preventing potential downgrade attacks.
  • Check your server’s TLS version and upgrade if necessary. Ensure you’re using at least TLS 1.2, as older versions are considered insecure.
  • Verify your website’s .htaccess file for proper HTTPS redirection. Add or modify rules to ensure all HTTP requests are redirected to HTTPS.
  • Implement proper Content Security Policy (CSP) headers. These headers help prevent mixed content issues by specifying which resources can be loaded.
  • Use SSL/TLS monitoring tools to regularly check your site’s security configuration. These tools can identify potential vulnerabilities before they cause issues.

At WeWP, we provide state-of-the-art website security. With automated SSL configuration and CDN optimization, you can enjoy worry-free website hosting.

Additional Preventive Measures

To keep your site secure and error-free, think beyond just fixing issues as they arise. Establish automated SSL certificate renewal to prevent unexpected expiration. Auditing to determine if the security headers for your website are timely enabled is essential. It will check for faulty setups of Strict Transport Security, Content Security Policy, and X-Frame Options. These are some of the essential security measures to improve your website’s security radically, blocking several types of digital attacks.

You also need a sturdy monitoring system. It should proactively detect when something goes wrong with your SSL/TLS settings before it affects your users. This includes certificate expiry, checking certificates for revocation, and proper support of the SSL/TLS protocol.

For WordPress hosting sites, consider using plugins that enforce HTTPS across your whole site. Install some additional ones to automatically fix mixed content issues. Adding an extra layer of Web Application Firewall (WAF) further increases protection against potential security threats.

CDN, WAF, CSP… sounds like a hassle? Let our team at WeWP take the strain.
