The “Not Secure” warning is a message displayed in web browsers to indicate that a website does not have a valid SSL/TLS certificate installed or that the website is not using HTTPS (HTTP Secure) to encrypt data transmitted between the server and the user’s device.
When a user visits a website with a valid SSL/TLS certificate and HTTPS enabled, their browser displays a lock icon in the address bar to indicate that the connection is secure. However, if the website does not have a valid SSL/TLS certificate or is not using HTTPS, the browser will display a “Not Secure” warning in the address bar, often accompanied by a red triangle or exclamation mark.
This warning is designed to alert users that any information they submit or view on the website is not encrypted and may be visible to others. As such, it is recommended that website owners install a valid SSL/TLS certificate and enable HTTPS to secure their website and protect user data.
To fix the “Not Secure” warning even though an SSL/TLS certificate is installed on your website, you can try the following steps:
Ensure HTTPS is enabled: Check that HTTPS is enabled on all pages of your website. Make sure all resources, including images, videos, and scripts, are also served over HTTPS. You can use a tool like the SSL Labs Server Test to identify any non-HTTPS resources on your page.
Check your SSL/TLS certificate: Verify that your SSL/TLS certificate is valid and correctly configured. You can use an online SSL/TLS certificate checker to verify your certificate’s status and configuration.
Complete the SSL/TLS certificate chain: Ensure that the SSL/TLS certificate chain is complete and all intermediate certificates are installed. You can use an online SSL/TLS checker to verify your certificate chain.
Configure non-www redirect: If you have a non-www redirect in place, make sure that your SSL/TLS certificate is valid for both the www and non-www versions of your website.
Update your web server: If you are running an older version of your web server software, update to the latest version. This will ensure that you are using the latest encryption protocols and security features.
Install a new SSL/TLS certificate: If your SSL/TLS certificate is expired or invalid, install a new certificate. You can obtain a new certificate from a trusted Certificate Authority (CA) such as Let’s Encrypt or DigiCert.
By following these steps, you can resolve the “Not Secure” warning on your website and ensure that your website is secure and trustworthy for your visitors.
