How To Disable Invalid SSL Certificate Warning On Your Web BrowserĮach web browser has a different SSL error message and has a different way to turn off this type of warning. Similarly, Mozilla Firefox browser will show 'Your Connection Is Not Secure,' and Microsoft Edge will display 'This site is not secure' as the error message. For example, if you use the Google Chrome browser, you will get this error message: Your Connection Is Not Private. However, if the web browser can't validate the SSL certificate, it will warn you about an unsafe website with different error messages, depending on which web browser you are using. When you browse a website through the HTTPS protocol, its SSL certificate is always verified by your web browser and then starts to establish a secure connection if it is valid. Why Does Your Web Browser Show An Invalid SSL Certificate Warning? This can be a server to a server, for example, a web-based application (that's stored in a server A) connects to a server B via the SSL method.

Note: The 'two systems' concept can be a client and a server, for example, a web browser and an online shopping store. When you purchase an SSL certificate from or, you actually purchase the most up to date TLS certificates. Not only me, but the majority of people are also now using the SSL term instead of the TLS term. I still refer to security certificates as SSL certificates because it's the most commonly used term. Nowadays, the first generation and outdated SSL version is no longer used. Transport Layer Security, or TLS, is an updated version of SSL, which is more secure. With this security technology, all your potential personal and financial information will be encrypted and invisible from criminals' eyes during transmission. It safeguards any sensitive data that is being transmitted from your web browsers to the webserver or vice versa.

A Secure Socket Layer, or SSL, is the standard security technology to establish a secure connection between two systems.
