This page is not secure broken https certificate missing, with users relying on websites to provide a secure browsing experience. However, when browsing the web, you may come across a “This page is not secure” warning. This message appears when the HTTPS (HyperText Transfer Protocol Secure) certificate is missing, broken, or improperly configured. The absence of a valid HTTPS certificate compromises security, potentially exposing users to data breaches and other cyber threats. In this blog, we will explore the importance of HTTPS certificates, what causes these errors, and how to resolve them.
What is HTTPS and Why is it Important?
HTTPS ensures that data transferred between a user’s browser and a website encrypted. Unlike HTTP (HyperText Transfer Protocol), which transfers data in plain text, HTTPS uses an SSL (Secure Sockets Layer) or TLS (Transport Layer Security) certificate to encrypt the connection. This makes HTTPS critical for protecting sensitive information such as passwords, credit card numbers, and personal data from being intercepted by malicious actors.
When a site is secured with HTTPS, users can trust that the data they share is protected. Moreover, search engines like Google prioritize HTTPS websites, making it essential for SEO. Websites without HTTPS certificates flagged as “Not Secure,” which can deter visitors and hurt your site’s ranking in search results.
Causes of a Broken or Missing HTTPS Certificate
There are several reasons a website may display a “Not Secure” warning due to a broken or missing HTTPS certificate. Let’s break down the most common causes:
- Expired Certificate
SSL/TLS certificates have an expiration date, typically ranging from one to two years. Once expired, the certificate no longer validates the security of the website. Browsers detect this expiration and alert users with warnings like “This page is not secure” or “Your connection is not private.” - Improper Installation
HTTPS certificates need to installed correctly on the server. If there’s a misconfiguration, such as not including the intermediate certificates, the browser will not trust the certificate, resulting in a broken HTTPS connection. - Certificate Authority (CA) Issues
SSL/TLS certificates issued by trusted Certificate Authorities (CAs). If the issuing CA is not trusted by the browser, or if the CA has been compromised, the website will be flagged as not secure. This can happen with self-signed certificates, which aren’t recognized by browsers. - Mixed Content Issues
Even if a website has a valid HTTPS certificate, if any content (images, scripts, stylesheets, etc.) is loaded over HTTP instead of HTTPS, the browser will show a mixed content warning. This partial protection can cause browsers to flag the site as insecure. - Missing or Incorrect Domain in the Certificate
SSL certificates must issued for the correct domain(s). If a certificate issued for “www.example.com” but the user tries to access “example.com” without the “www,” the browser will display a warning. Wildcard and multi-domain SSL certificates can help resolve this issue.
Consequences of a Broken HTTPS Certificate
A broken or missing HTTPS certificate can have serious repercussions, affecting both website owners and users. Let’s look at some of the key consequences:
- Loss of Trust
Users are unlikely to engage with a site displaying security warnings. A lack of trust can lead to reduced traffic and higher bounce rates as visitors quickly leave insecure pages. - SEO Impact
Search engines like Google have integrated HTTPS as a ranking factor. If your site does not have a valid SSL certificate, you could suffer in terms of search visibility and lose valuable organic traffic. - Data Vulnerability
Without HTTPS, sensitive data transmitted between the server and the browser exposed to hackers. This makes the site susceptible to man-in-the-middle (MITM) attacks, where cybercriminals intercept and manipulate communications. - Browser Warnings and Penalties
Major browsers like Chrome and Firefox are aggressive in warning users when a site lacks HTTPS protection. Over time, this can lead to decreased user engagement and traffic, as users may avoid sites that trigger warning messages. - Non-compliance with Regulations
Many regulations, such as GDPR (General Data Protection Regulation), require websites to ensure the secure handling of user data. A broken or missing HTTPS certificate may make your website non-compliant with such laws, resulting in fines and legal consequences.
How to Fix a Broken or Missing HTTPS Certificate
Now that we’ve identified the causes, let’s look at how you can fix HTTPS issues on your website.
- Renew the Certificate
If your HTTPS certificate has expired, you will need to renew it through your SSL certificate provider or CA. Make sure to enable auto-renewal if possible, to avoid future expiration issues. - Install the Certificate Correctly
Verify that your SSL certificate correctly installed, including intermediate certificates. Some tools, such as SSL Labs’ SSL Test, can help you diagnose installation issues and provide steps for fixing them. - Use a Trusted Certificate Authority
Avoid self-signed certificates for production websites. Instead, opt for certificates from trusted CAs. You can choose between free options like Let’s Encrypt or paid SSL providers like DigiCert or Comodo for more advanced options. - Address Mixed Content Warnings
Ensure that all assets on your website served over HTTPS, not HTTP. You can use tools like Chrome’s Developer Console to identify and update insecure content. Most modern content management systems (CMS) provide plugins that can automate this process. - Check Domain Mismatches
Ensure that your SSL certificate covers all the necessary domain variations, including subdomains if needed. Wildcard SSL certificates can secure multiple subdomains, while multi-domain SSL certificates can cover a variety of domains under one certificate. - Monitor for Issues
Regularly check the status of your HTTPS certificate using monitoring tools. Some services can notify you when your SSL certificate is about to expire or when mixed content detected.
Conclusion
This page is not secure broken https certificate missing, a broken or missing HTTPS certificate is more than just a technical inconvenience—it can undermine user trust, expose sensitive data, and hurt your website’s SEO ranking.
